The average baby will go through thousands—yes, thousands—of diapers in their lifetime. With that many diaper changes on the horizon, picking a quality baby diaper is critical. The best diapers keep your little one dry and comfortable, while preventing leaks and dreaded blowouts for parents to clean up. But with dozens of diaper types, features and brands for parents to sift through, finding the best baby diapers isn’t always easy or straightforward.

That’s where we come in. We did the dirty work (literally) for you, researching the leading diapers on the market and putting them to the test with real parents and real babies. The result is a comprehensive guide to baby diapers, including the best diapers for every budget, lifestyle and need. Keep reading to discover the top-performing options, including this year’s Best of The Bump winner.

Types of Baby Diapers

There are a few different types of baby diapers, each with their own merits. Deciding what works best for your family will depend on your preferences, lifestyle, budget and more. Here’s a brief overview to help you make the decision.

  • Disposables. As their name implies, disposable diapers are designed to be thrown away after they’re soiled. They make up the majority of the diaper market, with some studies reporting as many as 95 percent of US parents using them for their children—and it’s easy to see why. Disposable diapers are ultra-absorbent, which helps prevent diaper rashes and irritation, and convenient, as they don’t require any laundering or special care. However, the price of disposable diapers can add up, and many are non-biodegradable, with some 20 billion diapers entering landfills each year, according to the American Academy of Pediatrics.
  • Cloth. Reusable cloth diapers are typically made of cotton, fleece or other fabric. They also require a waterproof outer cover. They’re generally less absorbent, resulting in more frequent diaper changes, and require laundering—but they can be more cost-effective in the long run and environmentally friendly. (Though disposable diaper fans cite the energy and water required to launder cloth diapers, as well as the water required to produce cotton—both have negative impacts on the environment.)
  • Swim diapers. This option is a special type of diaper designed to catch any mess if baby goes no. 2 while in the water. Swim diapers don’t absorb liquid (otherwise they’d balloon from soaking up the water baby is swimming in), which means they won’t hold urine—they’re solely meant to contain poop. They come in both disposable and reusable forms.
  • Training pants. Also known as pull-ups, training pants are often used during potty training to help make the transition from diapers to underwear. They can be made of cloth or a disposable absorbent material, and typically feature stretchy sides—as opposed to the elastic fasteners found on diapers—that allow them to be pulled up and down like underwear.

What to Consider When Shopping for Diapers

The diaper that will work best for you and your family will depend on a variety of factors. “Many families make their choice based on the brand, design, cost and designations such as eco-friendly or organic,” says Caroline Brown, MD, a pediatrician based in North Carolina and mother of three young children. Here are certain things to consider before selecting a diaper for your child:

  • Fit. A diaper’s overall fit is one of its most important features, Brown tells us. Often, this takes some trial and error to discover which brand of diapers fits your little one best—but it’s worth the extra effort. “Some brands seem to fit some babies’ better than others, and the better the fit, the fewer the leaks or blowouts you’ll endure,” Brown says.
  • Materials. The materials used in a diaper are also an important consideration for parents, especially if baby has sensitive skin. If that’s the case, Brown suggests avoiding super absorbent polymers (SAP) and diapers that use chlorine or chlorine dioxide, as both could be potentially irritating to babies with sensitive skin. They might also do better with an eco-friendly or organic diaper, Brown says, as those are typically made with “materials like organic cotton or bamboo and are typically free of chemicals, such as chlorine, phthalates and synthetic fragrances,” she explains.
  • Cost. Brown points out that just because a diaper is more expensive, that doesn’t necessarily mean it’s superior to its more affordable counterparts. “Some less expensive brands may be a better fit for your child,” she says. “I encourage my patients’ parents to buy a package of a few different types to try before stocking up in bulk on a particular brand.”
  • Ease of use. Diapers need to be both baby- and parent-friendly, since the adults are the ones doing all of the diaper changes. Stretchy, tear-resistant tabs are one helpful feature for quick changes, and Brown particularly loves a wetness indicator on diapers (a line that changes color when the diaper is wet). “As a parent, I am a huge fan,” she says. “It can actually be difficult to tell if one of the super absorbent diapers is actually wet.”

How We Tested the Baby Diapers

To find the best diapers available today, we enlisted real parents—with children ranging in age from 2 to 19 months—to put the leading options on the market to the most demanding test of all. They used these diapers on their babies, during the day and overnight, and carefully assessed each one for ease of use; effectiveness; features and design; materials and ingredients; comfort and value for the money. We paired this testing with our own extensive research, as well as survey feedback from hundreds of parents in The Bump community, to determine the best diapers to meet every family’s needs and budget.

The Best Diapers to Buy

For more than 10 years, The Bump has acknowledged the best baby and pregnancy products on the market through our award series. Scroll down to see which diaper was named this year’s Best of The Bump award winner, along with a range of carefully vetted diapers to suit specific needs. Whether you want to take the cloth diaper plunge, find a good swim diaper or find the right fit for a newborn, we’ve got you (and baby) covered.

Overall best baby diapers

When it comes to baby diapers, Coterie reigns supreme—and for good reason. These diapers boast top-of-the-line materials, absorbency and leak protection, keeping babies up to three times drier than leading diaper brands, thanks to 70 percent more liquid capacity and four times faster absorbency. With this type of peak performance, it’s easy to see why Coterie earned this year’s Best of The Bump award. (Head here to see all of this year’s Best of The Bump winners.)

Our product tester, who gave Coterie 5 out of 5 scores in a wide range of categories, including ease of use, effectiveness, features and design and comfort, was amazed by the diaper’s overall performance. “The diapers were extremely absorbent—better than any diaper I’ve used,” she said. “They didn’t leak once. No blowouts escaped them. I used them during the night where [my baby] would go a 12-hour stretch without being changed and still never had any leaking through.”

Not only do these baby diapers work exceptionally well, they’re also soft to the touch and made with apparel-grade fabric and hypoallergenic, dermatologist-tested materials. In fact, Coterie diapers are free of more than 200 potential irritants, including fragrance, alcohol, chlorine and latex. “The diapers felt very soft and stretchy,” our product tester reported. “It felt like really soft, thick toilet paper … [my baby] never seemed uncomfy in them, and they never left any red marks or irritation from the diaper leg cuffs like I’ve noticed other diapers have.”

With their extraordinary leak and blowout protection, cleaner ingredients and super-soft materials, Coterie diapers are easily the top pick of parents and babies, and the winner of a well-deserved Best of The Bump badge.

Size range: Newborn (under 10 lbs.) to 6 (35+ lbs.) | Materials: Polypropylene, polyester and polyethylene (backsheet); propylene (topsheet); SAP and wood pulp (core) | Wetness indicator: Yes

“I’d recommend these for two reasons: Because they never once leaked, and because my baby’s skin was not irritated once.”

Best cloth diapers

bumGenius Freetime 2.0 All-in-One Cloth Diaper
Image: bumGenius
Buying Options

Love the concept of cloth diapers, but intimidated by the process? The Bumgenius All-in-One Cloth Diaper makes it easy on parents—both those familiar with cloth diapers and those that are brand new to the practice. While cloth diapers traditionally require an additional waterproof cover, the Bumgenius has combined the absorbent cloth inserts and waterproof outer shell into a one-piece design that keeps things simple. The snap closures allow for quick and easy changes, as well as the ability to customize the size to fit baby. “The Bumgenius made changing diapers simple and quick,” said our product tester, who rated this diaper a 5 out of 5 for ease of use. She added, “I loved the fitting of the diaper. I was able to adjust the snaps for the perfect fit.”

Not only is the bumGenius simple for parents to use, it’s also effective at keeping babies dry and comfortable. So if you’re worried that a cloth diaper won’t deliver on absorbency, let our product tester set your mind at ease: “The effectiveness of the bumGenius All-in-One cloth diaper was outstanding. We didn’t experience any leakage from anywhere while wearing the diaper,” she gushed, rating the bumGenius 5 out 5 not only for effectiveness, but also for comfort and materials and ingredients. “I usually dread trying out new diapers, because we haven’t had much luck with other diaper brands,” she told us. “My daughter has sensitive skin so we always have to be careful with what brands and material we use. We haven’t had any issues since using bumGenius.” Performance and simplicity from a cloth diaper? Sign us up!

Size range: One size (fits 8 to 35 lbs.) | Materials: 100% laminated polyester (outer shell); 100% polyester (inner); 100% cotton (absorbent layers); 74% polyester/15% nylon/11% spandex (tabs) | Wetness indicator: No

“BumGenius is a great cloth diaper brand, and I would definitely recommend it to other parents—the number one reason being that they’re perfect for babies and toddlers. I love that you’re able to reuse them as your baby grows.”

  • Six layers of sewn-in cotton for maximum protection and comfort

Best newborn diapers

Newborns can use up to 10 diapers a day —but Huggies Little Snugglers helps make those diaper changes a breeze. These newborn diapers earned top scores—a full 5 out of 5—for ease of use from our product tester, who said that they were “very easy to put on and take off” her 2-month-old. And while parents and caregivers appreciate their user-friendly design, newborns will love the softness of Huggies Little Snugglers Diapers against their fresh baby skin. “The inner lining was textured and very soft,” our product tester reported. “I could appreciate that my baby was comfortable.”

The fit and comfort were singled out for praise by our survey respondents, one of whom told us, “The fit is really nice and not irritating for baby.” Little Snugglers feature a curved shape that helps to conform to a newborn’s tiny body, as well as an umbilical cord cutout to protect their healing belly buttons. “The adhesive tabs are stretchy,” our product tester told us. “They worked to secure the diaper, which stayed in place throughout day and night.”

The absorbent liner keeps moisture away from your newborn’s sensitive skin, and the core protects against leaks for up to 12 hours. This was also a standout feature for our survey respondents, who praised the diaper’s absorbency for both day and night use. Easy-to-use, soft and gentle with excellent absorption—what more could you want from a newborn diaper?

Size range: Preemie (under 6 lbs.) to 6 (35+ lbs.) | Materials: Wood pulp, polypropylene, polyethylene, sodium polyacrylate and polyester | Wetness indicator: Yes

“They have good absorbency and work good for day and night. The fit is really nice and not irritating to baby.”

What We Love
  • Umbilical cord cutout to protect baby’s healing belly button
  • Wetness indicator
  • Soft elastic waistband helps keep blowouts contained
Things To Consider
  • Legs are narrow

Best preemie diapers

When baby is born prematurely, it’s hard to imagine a diaper made small enough to fit their tiny bodies. That’s where Pampers Swaddlers come in: Pampers worked with NICU nurses to develop a line of preemie diapers designed to fit even the smallest of babies. The diapers are available in three different preemie sizes, ranging from P1 (for babies under six pounds) to P2 (for babies four pounds and under) all the way to P3 (which fits babies smaller than one pound, eight ounces). The P3 size was the first of its kind from a major brand. With this variety of tough-to-find sizes, Pampers Swaddlers ensure that there’s a diaper to fit every baby, no matter how early they arrive.

In addition to their size range, Pampers Swaddlers also offer supreme leak protection for hours, thanks to dual leakguard barriers along the legs and a blowout barrier along the waistband. Our product tester found the absorbency in these diapers to be impressive, particularly for overnights. “They work very well overnight,” she reported. “We haven’t experienced a leak at night, and [it] was easy to change them in the morning without any surprises.”

“These diapers seemed comfortable for my baby,” our tester added. “They are pretty soft but also durable.” Welcoming a baby before their due date is stressful enough, but, thankfully, finding a diaper that fits them well (and works well too) doesn’t have to be.

Size range: P3 (under 1 lb., 8 oz.) to 8 (46+ lbs.) | Materials: Polypropylene and spandex (leg cuffs); wood pulp (absorbent fluff); polypropylene and stretch film (fastening system) | Wetness indicator: Yes

“My baby seemed very comfortable having his diaper changed with the Pampers Swaddlers.”

What We Love
  • Accommodates babies as small as 1 lb. 8 oz.
  • Double leg cuffs for a snug fit
  • Hypoallergenic and free of parabens and latex
Things To Consider
  • Tester reported some daytime leaks during active hours

Best overnight diapers

Huggies Overnites Nighttime Baby Diapers

It’s a major parenting win when baby starts sleeping through the night, and one that shouldn’t be interrupted by a leaky diaper. A quality overnight diaper needs to be absorbent, secure and comfortable—and Huggies Overnites Nighttime Baby Diapers excels in each of these areas. Our product tester gave Overnites perfect 5 out of 5 scores in effectiveness, features and design, and comfort, telling us, “My baby girl had no irritation or redness after wearing them at night. She seemed very comfortable wearing them!”

Our product tester was especially wowed by the absorbency of Huggies Overnites, a key factor in keeping babies dry all night long. They feature double grip strips to keep the diaper in place (even as your little one tosses and turns) and a contoured fit to prevent any gaps where leakage can escape. “I didn’t experience any leakage with my one-year-old,” our product tester shared. “They worked a bit better than our regular daytime diapers because of the extra stretch and absorbency!”

With Huggies Overnites, babies are not only kept dry, but also comfortable all night long. The dry touch liner prevents little ones from feeling wet overnight, and the diaper is designed to be extra soft against their skin—a feature that stood out to our product tester. “The Huggies nighttime diapers felt very soft and gentle on my baby's skin,” she shared. With their ability to keep babies dry and comfy overnight, Huggies Overnites are the clear top choice for an overnight diaper.

Size range: 3 (16-28 lbs.) to 7 (41+ lbs.) | Materials: Wood pulp, polypropylene, polyethylene, sodium polyacrylate and polyester | Wetness indicator: Yes

“I would highly recommend the Huggies nighttime diapers to other parents! They are extra soft, stretchy and absorbent, so they’re great for a good night’s sleep!”

What We Love
  • Double-grip fasteners keep the diaper from shifting during sleep
  • Stay-dry liner keeps moisture away from baby’s skin
  • Adorable Winnie the Pooh prints
Things To Consider
  • Size range is more limited than some options

Best eco-friendly diapers

Love the convenience of disposable diapers but not their impact on the environment? Eco-friendly diapers are an excellent alternative for parents who aren’t ready to make the jump into cloth diapers—and our favorites are Andy Pandy Bamboo Disposable Diapers.

Andy Pandy diapers are made from bamboo viscose that’s good for both the environment and baby’s skin. The bamboo is grown without pesticides or chemical fertilizers and is up to 87 percent biodegradable—while also being super absorbent and gentle for your little one. These eco-friendly diapers also feature pure aloe essence, which helps to keep baby’s skin soothed and protected against diaper rash. “I really love that they put pure aloe, because it seems to help keep baby skin soft and smooth,” our product tester said, giving Andy Pandy a 5 out of 5 score for comfort.

Of course, eco-conscious design is all well and good, but the diaper still has to work right. Thankfully, our product tester loved how absorbent and comfortable they were for her baby, telling us, “He felt comfortable with his diapers and slept well with them too.” Even better, our tester reported that while her baby has sensitive skin, “he never got a diaper rash when using these diapers.” She also praised the fit: “These diapers have been very easy to take off and put on my baby,” she told us “I really loved how stretchy they are and how easy it is to adjust the tabs. It was never too tight or too loose.” Good for the earth, good for baby and good for eco-conscious parents? That’s a diapering trifecta right there.

Size range: Newborn (7-10 lbs.) to XL (26+ lbs.) | Materials: Bamboo viscose, chlorine-free fluff pulp, SAP | Wetness indicator: Yes

“These were so soft on baby’s bottom and I loved that about them. It seems that my baby has sensitive skin, so these really helped with diaper rashes.”

What We Love
  • Naturally hypoallergenic and antibacterial
  • Free of chlorine, alcohol, preservatives, phthalates, latex, PVC and TBT
  • 5% discount with subscription
Things To Consider
  • Product tester reported they were loose around the legs
  • They can smell once baby pees

Best cheap diapers

Looking for a diaper with an affordable price tag that doesn’t sacrifice performance? Look no further than Luvs disposable baby diapers, which are a great option for parents looking for a wallet-friendly choice. Luvs average around 17 cents per diaper, nearly 10 cents cheaper than other name-brand competitors—and with the number of diapers you’ll buy throughout your child’s lifetime, those pennies add up fast.

But Luvs aren’t cheap when it comes to quality; they hold their own on the performance front as well. Luvs Ultra Leakguards earned 5 out of 5 scores for ease of use, features and design, effectiveness and (of course) value for money—but one area that particularly stood out to our product tester was their absorbency, despite feeling thinner than diapers she had used in the past. “They have worked perfectly throughout the day and night,” she gushed. “It was also very absorbent!”

Luvs’ triple leakguards offer three absorption areas to help keep baby feeling dry, and are infused with aloe to help soothe your little one’s skin. “My baby had no irritation or reaction to them and seemed very comfortable and happy wearing them,” our product tester reported. Top performance at a low price? That’s a win-win for parents and babies.

Size range: Newborn (under 10 lbs.) to 7 (41+ lbs.) | Materials: N/A | Wetness indicator: Yes

“I never used Luvs diapers before, and I was pleasantly surprised. They’re very user-friendly, even with a wiggling baby!”

What We Love
  • Affordable
  • 100% hypoallergenic and free of parabens and latex
  • Infused with aloe extract
Things To Consider
  • Thinner than some of the competitors

Terra|$13.95 for 24

When baby has sensitive skin, you need a diaper that won’t add to their irritation or discomfort. Enter Terra diapers, which are designed with high-quality, plant-based materials—and without any harsh chemicals or fragrances—to keep even the most sensitive of baby skin feeling happy. Our product tester was wowed by the materials and ingredients used in Terra diapers, rating them a 5 out of 5 in the category. “My baby has very sensitive skin, so I was really pleased with that aspect of the diaper and the ingredients used to make it,” she explained. “It was really soft, fragrance-free and felt great—which can be unique among eco-friendly diapers.”

Another key factor for babies with sensitive skin is keeping their skin dry to prevent rashes. The absorbent core used in Terra diapers feature high-quality Japanese SAPs that help to wick away moisture faster and keep baby feeling drier for longer. Our product tester reported that her “baby felt dry to the touch when changing” and experienced no redness or irritation from the diapers, giving them 5 out of 5 for comfort.

Terra doesn’t stop there, however; they’re also an eco-friendly choice. Terra diapers are made out of 85 percent plant-based materials, and even the packaging is plastic-free (it’s made of biodegradable craft paper and rice). Whether your child has sensitive skin or not, Terra Premium Diapers are an impressive choice all around.

Best diapers for blowouts

Rascal + Friends Premium Diapers
Image: Walmart

Let’s face it: Diaper blowouts are fun for no one. But certain diapers are better at handling those messes than others, and our favorites are Rascal + Friends Premium Diapers. Designed by a mom of four from New Zealand, these diapers feature a stretchy waistband (designed to sit higher on baby’s back to prevent those up-the-back accidents) and an extra-deep pocket (to catch even the biggest of blowouts). Also keeping those messes secure is an ultra absorbent core that can hold up to 15 times its weight in liquid. And these features don’t just sound impressive, they deliver the goods: Our product tester reported no leaks or blowouts—even when worn overnight.

Rascal + Friends Premium Diapers are also gentle on baby’s skin, as the diapers are made without any harsh chemicals, latex, lotions or fragrances (all potential irritants). “I was comfortable putting my sensitive baby in them,” our tester said, “and she did not have any irritation.” And while all of those are important considerations when selecting a diaper, the most standout feature of Rascal + Friends is their ability to contain even the yuckiest of diaper explosions. Your child—and your laundry pile—will thank you.

Size range: 1 (6-11 lbs.) to 7 (37+ lbs.) | Materials: Fluff pulp, SAP, polypropylene and polyethylene | Wetness indicator: Yes (in sizes 1 to 2)

“These diapers were very effective—I had no leaks or beyond-the-diaper blowouts even when worn overnight.”

What We Love
  • No lotion, no latex and no fragrance
  • Affordably priced
Things To Consider
  • Not sold in most stores

Best training pants

Target|$19.99 for 60

Have a little one who’s not quite ready for underwear but eager for something less baby-ish than diapers? Training pants are a perfect middle ground, allowing your toddler to feel like they’re wearing undies while still protecting against accidents. We’re big fans of Millie Moon Luxury Training Pants—which earned a whopping 5 out of 5 score from our product tester across all categories.

A standout feature of the Millie Moon training pants is the DreamFit waistband, which is made of 15 individual pieces of elastic to move closely and comfortably with your ever-busy toddler. “These training pants had a lot of great features, such as the extra stretch in the waistband,” our product tester shared. “They fit great around her waist thanks to the stretchy material.” Another smart design in the Millie Moon training pants is the resealable tab, which allows parents to roll the training pants and seal them closed for disposal (keeping any messes contained). Our product tester called it her favorite feature, noting how it “makes disposing [of] them so much easier.”

Millie Moon Luxury training pants are also fragrance-free, lotion-free, latex-free and dermatologically tested, to keep your toddler’s skin protected from any potential irritants. “These training pants felt like clouds, they’re that soft,” our product tester gushed. “She was able to wear them and run around all day without showing any signs of irritation.” Our tester even said they helped with potty training, by getting her daughter used to taking off and pulling on an underwear-like product. So although we love Millie Moons, here’s hoping she won’t need them much longer!

Size range: 2T/3T (22-33 lbs.) to 4T/5T (35+ lbs.) | Materials: N/A | Wetness indicator: Yes

“I would definitely recommend these training pants. The comfort and features like the resealable tab, the extra stretchy waistband and the double cuff make these training pants worth the price.”

A day of fun in the sun can quickly be ruined by a diaper malfunction—but those can be easily prevented by a quality swim diaper. The best in the category? Pampers Splashers, which excel at keeping messes contained and baby comfortable while taking a dip. “These diapers worked perfectly for the pool and the beach,” our product tester told us, giving Pampers Splashers 5 out of 5 scores for effectiveness. “We had no leakage issues, and I felt confident that we wouldn’t. They worked perfectly in the water and while my baby crawled around on the sand.”

Two other areas where Pampers Splashers rated perfect 5 out of 5 scores from our product tester were features and design, and ease of use. She raved about the diapers’ stretchy waistband and elastic cuffs, which provide a secure fit and protection against blowouts. “They fit like a glove,” she shared. “The diaper had elastic in the legs and the waistband and I loved it. These were the most secure swim diapers I have ever tried, and I really felt confident that my baby was comfortable but also that we were safe from leakage.”

Our product tester went as far as to claim Pampers Splashers were her “favorite of any swim diaper we have tried,” adding, “they gave us the protection we needed to have a good pool or beach day.”

Size range: Small (13-24 lbs.) to large (31-40 lbs.) | Materials: Wood fluff pulp, polypropylene and spandex | Wetness indicator: No

“I honestly preferred these swim diapers to others we have tried in the past. These diapers were amazing.”

How We Chose the Best Diapers

To help you find the best diapers on the market today, The Bump editors did extensive research to identify the most popular, effective and environmentally friendly products out there, combing through user reviews, leveraging our familiarity with leading diaper brands and relying on our own experiences as parents. And then we put those diapers to the test. We enlisted the help of real parents who used these diapers with their own babies during both day and night, at home, at the playground and even at the beach. They then carefully evaluated each for ease of use, effectiveness, features and design, materials and ingredients, comfort for their baby and value for the money.

Pairing this rigorous testing protocol with our own expertise and insights, as well as survey data from hundreds of members of The Bump community, we bestowed the prestigious Best of The Bump award to the overall best diaper. And then we used the testing results to identify other standout options that are particularly good for particular needs, whether you’re seeking out a diaper that’s eco-friendly, great for sensitive skin, affordable and more. Because you, baby and their tiny tushie all deserve to be happy.

Do Diapers Expire?

No, diapers don’t technically expire, but you may want to use them up sooner rather than later. “Diapers do not have a specific expiration date per se,” Brown explains, “but they may become less effective over time.” The absorption material can break down over time, causing the diaper to soak up less liquid—potentially resulting in leaks or diaper rashes.Plus, the adhesive found on the diaper tabs can weaken over the years, which could cause the diaper to not be as secure on your little one. Most disposable diaper manufacturers recommend using baby diapers within the first two years of purchase. But don’t stress if you open a pack that’s not super fresh: While using an old diaper might not be as effective, it’s not harmful to your child.

When Do Babies Stop Wearing Diapers?

Already looking forward to the day your little one is out of diapers? According to the AAP, most children in the US begin potty training sometime between 2 and 3 years old—and most are “bowel and bladder trained by 4 years of age.”

But just because you’ve conquered potty training doesn’t mean it’s time to ditch all diapers just yet. Dryness at nap times and nighttime often happens later than daytime toilet training. “Some children need diapers or pull-ups for nighttime bed-wetting for several years,” Brown says. She points out that some children will be unable to stay dry through the night until they’re around 6 or 7 years of age (and even older, in some cases).

However, there are no hard and fast rules as to when babies officially stop wearing diapers. Potty training is dependent on a variety of factors—but if you ever have concerns about your child and their toileting habits, be sure to talk to your child’s pediatrician.
