11 Reasons Why Babies Cry—And How To Soothe Their Tears

The key to calming a crying baby is understanding what’s prompting those tears in the first place. With the help of experts, we break down the common culprits.

When it comes to babies, there are few absolutes. After all, no two babies are alike, and what works for one may not work for another. But there is one thing all babies have in common, and that’s a tendency to cry. The extent of those little wails will of course vary from child to child, but most new parents can expect to deal with one to three hours of baby crying every day. Why? Because it’s baby’s early—and only—way of communicating her needs and wants. There may not be a Google Translate option to help figure out what a crying baby is trying to tell us, but there are some common reasons why babies cry. Read on to learn how to decipher baby’s cries, plus helpful tips for soothing those tears.

Why Do Babies Cry?

If you have a crying baby on your hands, chances are he’s trying to tell you he’s in need of something. Evolutionarily speaking, offspring of mammals cry as a signal to their parents that they need immediate attention, says Darcia Narvaez, PhD, a professor of psychology at the University of Notre Dame in Notre Dame, Indiana. Here, we’ve identified 11 of the most common reasons why babies cry, along with some strategies for how to calm a crying baby.

1. Hunger

They call it “hangry” for a reason. Everyone gets a little cranky when they’re hungry, especially babies: They can go from zero to screaming pretty quickly if they haven’t eaten for a while. You might recognize the “feed me” cry as rhythmic and repetitive and (usually) short and low-pitched. Baby’s hunger cries may also include a “neh” sound, says George Betsis, cofounder of Dunstan Baby Language, an organization dedicated to understanding baby cries. This stems from baby’s tongue reflexively hitting the roof of his mouth in his search for milk.

The key with feedings isn’t to watch the clock—it’s to respond to baby’s cues. “Crying is a late sign of hunger,” says Paul Horowitz, MD, a pediatrician with Discovery Pediatrics in Valencia, California. To prevent baby crying from hunger, look for early signs he’s ready for a nosh: lip-smacking, sucking on his hands or rooting ( aka turning his head to find the breast or bottle).

2. Sleepiness

As an exhausted parent, you may be able to fall asleep the minute you hit the mattress, but the same isn’t necessarily true for baby. Sleep is a learned skill, just like anything else. “Newborns don’t have an established circadian rhythm until around 4 months,” says Kim West, LCSW-C, author of The Sleep Lady’s Good Night Sleep Tight: Gentle Proven Solutions to Help Your Child Sleep Well and Wake Up Happy “On top of that, a crying baby is largely incapable of self-soothing, so parents have to help baby establish these things.” To help reduce baby crying at night and soothe her to sleep, a little trial and error is likely in order to see what calms your tired baby best. Swaddling, for starters, may make your little one feel cozy and comfy. Some babies also respond well to rocking motion, the sound of a lullaby or even a hum of the vacuum.

If baby is crying at night and waking frequently, it can be tempting to cut down on daytime sleep, thinking fewer afternoon naps will help baby sleep better at night—but it won’t. When baby is overtired, her body will produce hormones that give her a second wind, making it harder to fall and stay asleep. Even if it’s not baby’s usual naptime, if she seems tired, go ahead and put her down. “Sleepy babies should be allowed to sleep,” Horowitz says.

3. Dirty diaper

Some babies can sit in a wet or dirty diaper for hours without a care in the world. Others go nuts if they’re uncomfortable for more than a second. (Can you blame them really?) Take a second to open up the diaper and do a quick check or perform a “sniff test.” You can also opt for a diaper brand that comes with a wetness indicator, like Huggies Little Snugglers, which change color when the diaper is wet. That way, you don’t have to undress your child every time you need to investigate whether that baby crying is due to diaper discomfort.

4. Need to burp

If you notice baby crying right after feeding, that’s a classic sign he needs to be burped. But there are other times a good burping may be in order. “Everyone remembers to burp baby after a feeding, but many babies may need to be burped after sucking a pacifier, having the hiccups or crying,” Horowitz says. “All these activities can result in swallowing air.” So, when you have an inexplicably crying baby, it doesn’t hurt to give him a pat on the back. There are several techniques for how to burp a baby out there, so find one that works for you. “I hold baby over my left shoulder, making sure his left arm is hanging over my shoulder,” Bumpie KatieDahlia says. “Then I rub in circles on his left side and back, starting down by his hip and working up. Usually after two or three tries, we get a massive burp out of him.”

5. Tummy troubles

Is your crying baby also wriggling, arching her back or pumping her legs? These are telltale signs of baby gas, says Preeti Parikh, MD, a pediatrician at Pediatrics of New York in New York City. The good news is there’s an easy way to help her pass it. “Hold baby on the left side or on her stomach to help with digestion,” Parikh says. “If baby is gassy, bicycle her legs and push them up to her chest to help relieve the gas.”

6. Teething

Baby can start teething as early as 4 months old, and when the pain sets in, an uptick in baby crying is pretty much guaranteed. Other signs of teething are excessive drooling and gnawing on anything within reach. “Sucking either on a pacifier or on your thumb or finger can help soothe baby,” Parikh says. You may even want to give your crying baby a gum massage, Horowitz suggests: Just massage the gums until your finger makes a squeaky sound. Chewing on frozen or refrigerated teethers, washcloths or even cotton bibs can also give baby some relief.

While it may be tempting, steer clear of over-the-counter teething aids like Anbesol or Orajel. These benzocaine-based products are no longer approved for use by the American Academy of Pediatrics, since they can numb the back of the throat and interfere with baby’s ability to swallow. In addition, the US Food and Drug Administration warns parents about the dangers of homeopathic remedies, such as teething tablets. When it comes to soothing a crying baby’s teething pains, natural relief is best, unless baby is truly miserable. In that case, Tylenol and Motrin in weight-appropriate doses are the only recommended medications for teething in babies these days, says Eugenie Charles, MD, a pediatrician in the pediatric emergency room at Inova Loudoun Hospital in Leesburg, Virginia.

7. Overstimulation

We all get sensory overload now and again. For baby, it might be after getting passed around by aunts and uncles at a family party, or toted along to the grocery store. Remember: Your little one is still getting used to all that commotion, so it might not take much to get her upset. It’s a good idea to take a crying baby home and relax when she seems overstimulated. Going for a walk and getting some fresh air in a quiet, familiar setting can also do her some good, Parikh says. But don’t go too crazy trying to keep her away from sensory activities. “Stimulation is a good thing,” Horowitz explains. “The best form of it for baby is one-on-one stimulation with a loved one.”

8. Need for attention

We all know babies don’t exactly operate on the “set it and forget it” mentality. You can (and should!) have baby spend some quiet alert time on a playmat or in a safe baby swing or bouncer. But your child will be happiest and most quiet when he’s with you. “Babies often cry out of loneliness because they’re not being held or rocked constantly. They need these things as they go through this period of rapid development,” Narvaez says. “Young babies should be attended to empathically and quickly so their systems learn to be calm instead of agitated or aggravated.”

9. Illness

No one likes being sick and miserable, babies included. If your little one is feeling ill, you’ll likely notice baby crying more often than usual. “Most parents know what baby's usual cry sounds like, so if baby won’t stop crying or is crying harder and longer than usual, it could be a sign of illness,” Charles says. “Also look for other symptoms, like fever, vomiting, lack of weight gain, if baby’s not alert or if baby is inconsolable,” and bring it to your pediatrician’s attention.

10. General discomfort

When we have an an eyelash stuck in our eye, a hair wrapped around our toe or a clothing tag that’s rubbing against our skin, we can simply remove it. But a preverbal baby has only one way to let you know she’s uncomfortable, and that’s—you guessed it—crying. If your child is still unhappy after napping and being fed, burped and changed, “strip baby down and inspect for itchy tags or other small things that could be wrong,” West says. Even a too-tight shoe can cause a meltdown, so use your best sleuthing skills here.

11. Colic

Last but certainly not least on the list is colic, the pièce de résistance of baby crying. Colic is defined by the American Academy of Pediatrics as a condition where an otherwise healthy infant cries more than three hours a day, more than three days a week, for more than three weeks in a row. Babies with colic cry excessively, are more difficult to console and have disrupted sleep, leading to a whole lot of stress for you and your partner. But it’s important to remember that colic is usually pretty short-lived. Plus, colicky babies aren’t necessarily uncomfortable or in pain, Charles says, and it doesn’t mean you’re doing anything wrong. Often, it’s just baby’s way of dealing with life during those early months.

How to Calm a Crying Baby

The best way to soothe a crying baby is to first have an idea of why is baby crying, so you can quickly address his needs. Without knowing what’s causing those tears, parents often try a bunch of different calming techniques, Betsis says, but in doing so, they often miss the window of opportunity to solve the real problem, and the baby crying escalates. If you still have a crying baby on your hands after checking for all the common culprits mentioned above, try the “Five S’s”—general soothing techniques pediatrician Harvey Karp, MD, outlines in his book Happiest Baby on the Block. Here’s a breakdown of how to make baby stop crying using these helpful tips and tricks:

Swaddle. Babies love to be swaddled. It provides them with a sense of security and reminds them of their days in the womb. The first step to soothing your crying baby is to wrap them in a snug (but not too tight!) swaddle with baby’s arms at her side.

Side or stomach position. Hold baby on his side or on his tummy over your arm. Both positions are comforting for baby and can help resolve gas and other tummy issues.

Shush. Make a gentle shushing sound directly into baby’s ear, which is similar to the noises she heard in the womb. Don't be afraid to amp up the volume a bit for a crying baby.

Swing. Try swinging or gently jiggling baby to get him to calm down (while always taking care to support baby’s head and neck). Babies are used to these types of motions from their time in utero and can be startled by stillness shortly after birth.

Suck. According to Karp, a lot of fussy babies deeply relax when they suck on something. Try nursing or using a pacifier once baby starts to calm down a bit.

When to Let Baby Cry It Out

It’s hard for any parent to hear baby crying, and it’s instinctual to want to soothe those tears. But is there ever a point when it’s best to just let baby cry? There’s really no hard-and-fast answer. Yes, babies can cry a lot, but given that it’s their primary form of communication, it’s not all that surprising. “They need to learn the rhythms of living outside the womb, and they need lots of help with that—through comfort, rocking and calming,” Narvaez says. “They can't do these things themselves during the first several months.”

When it comes to sleep training, whether or not it’s okay to let baby cry it out—otherwise known as the Ferber method—is a bit controversial. Some critics say letting baby cry can be emotionally scarring, but that claim isn’t backed by science. In fact, a 2016 study found that letting baby cry didn’t result in any stress responses or have any long-term effects on baby’s emotional state, outward behavior or the parent-child bond. But every family has to find a sleep training strategy that works for them. If you do opt to let baby cry it out, experts agree the child should be at least 6 months old—but that doesn’t mean your little one can’t learn some self-soothing techniques in the meantime. “It’s not harmful for baby to fuss a bit while you grab a quick shower, as long as he’s in a safe place,” West says.

If baby won’t stop crying and you’ve reached your limit, it’s always okay to put your child down in a safe place, like the crib or play yard, walk away and take a few minutes to compose yourself. If you feel yourself starting to get frustrated and angry with your crying baby, take a step back and find someone to help, whether it’s your partner, a family member or a friend. And remember, as with all things, this too shall pass.
