How to Teach Baby 29 Important Words in Baby Sign Language
It can be hard to hear baby’s cries—and when they’re too young to speak, it can be hard to know exactly what your little one wants. Are they hungry? Tired? Do they need a diaper change? Not to mention, it’s probably just as frustrating for baby when they’re doing their best but can’t get their message across. In recent years, many parents and caregivers have been turning to baby sign language to help bridge the gap in communication with their preverbal infant. “I’ve been signing milk and saying ‘milk’ before feedings for about a month now…I’m not sure if she recognizes the signal or the word but she definitely knows that means she is going to eat,” shares The Bump community member SportyMrs.23. “I thought it would be too early for her to recognize,but she really seems to understand that one sign.”
You’d be surprised at how quickly—and how much—babies pick up when it comes to basic sign language for babies and communication. Here, learn from experts what sign language for babies is, its benefits, how to start teaching it and the best common baby signs to know.
- Baby sign language has become a popular tool for parents to communicate with their pre-verbal infants. It’s best to start signing to them when they’re between 4 and 6 months old.
- While babies will not be able to sign back until they’re between 6 and 9 months old, they’ll start to form connections between the sign, the verbal word and the action or object both represent.
- Start by picking a core set of signs you’ll use frequently and add them into daily, low-stress routines. Repetition and consistency are key in teaching baby sign language.
- There’s no set age to stop signing to baby; you can keep doing it for as long as you like—but baby will probably start using words over signs to communicate more efficiently once they’re able to.
Baby sign language is a set of simple hand gestures and movements, otherwise known as signs, that correspond to common words you use with baby every day. It’s a helpful tool to enhance communication between hearing parents and babies who can hear but can’t yet talk. Sometimes the baby signs are the same as those used in American Sign Language (ASL), but not always. “Baby sign is not a technical sign language, such as ASL or BSL (British sign language), which are primarily used by the deaf community and are more complex, with grammar and sentence structure,” says Jann Fujimoto, CCC-SLP, a certified speech-language pathologist in Wisconsin. “It’s a looser version that uses just signs for individual words.”
Academics began making powerful observations about how hearing families could benefit from using baby sign language around 200 years ago, thanks to the work of linguist William Dwight Whitney in the 1800s. But it wasn’t until the 2000s that baby sign language became readily available to parents through workshops, classes and baby sign language books.
If you’ve decided to give baby sign language a go, you may be wondering when to teach baby some signs. A good time to start is when baby is 4 to 6 months old, according to Fujimoto. They’ll start to show an interest in communicating and start making signs on their own by the time they’re about 6 to 9 months old, says Melissa White, CC-SLP, managing director of clinical services at VocoVision. “This is when babies are developing the pre-requisite skills for communication, such as joint attention, which helps children track movements and early gestures to communicate.”
While your little one likely won’t start making signs on their own right away, eventually baby will start to make connections between the word, sign and item. Just like learning a foreign language, a preverbal baby is going to understand more than they can speak—or in this case, sign—at first. “Don’t underestimate your baby’s ability to understand long before they’re able to communicate that understanding to you,” shares The Bump community member LC122.
There are many different approaches to teaching baby sign language. Below, experts list their tips for how to start signing to your little one:
- Sign and say the word simultaneously: Teach baby by saying a word like “milk,” while making the sign at the same time, and then giving baby the milk. “Don’t hold out the item as a prize and refuse to hand it over until your child makes the sign themself,” Fujimoto says. “Verbal reinforcement—by saying the word while also showing the sign—as well as consistency are key.”
- Be consistent with it: As part of the consistency, you’ll want to use the signs every day for baby to truly understand them. “When introducing any new skill, repetition and patience are key,” White says. “Start by finding daily routines that work for you.” These should be moments that are low-stress so that signing to baby doesn’t feel overwhelming. Once you pick your moments, identify your core signs to keep it manageable. “For example, you can choose to incorporate signs like ‘milk,’ ‘more,’ or ‘all done’ during mealtime, since this gives you plenty of chances to practice with your baby,” White adds.
- Utilize external resources: These days there are tons of workshops, videos, books and apps available, all designed to help you teach sign language for babies. A typical class or workshop may teach parents 30 to 50 different signs you can then use with baby at your own pace. “Some families with older babies may learn best by signing along with a video, or attending a class together,” Fujimoto says. “Families should find the method that makes sense for them.” Just be sure to use a method “created or recommended by reputable early childhood organizations and professionals,” White adds.
- Respond to baby: As baby starts to connect the words, signs and actions or objects, they’ll start to attempt signs. When they do this, “respond right away with the action or object they’re requesting,” White says. “This kind of immediate feedback strengthens the connection and motivates them to keep communicating.”
I've introduced milk, change, sleep, tired and finished—and he's already starting to recognize milk. I've also halfheartedly introduced mommy and daddy. Just use the sign anytime you do the action/refer to the thing. Once our son really starts solids, we'll add in eat and more…I also sign the alphabet and numbers for him during the day, mostly because he loves watching my hands move.
When you’re ready to begin teaching baby sign language, you’ll need to decide which baby signs to start with. Fujimoto says to choose the words you and your family use the most on a day-to-day basis, like “more,” “please” and “milk.” Ready to learn how to teach baby sign language? Brush up on the below illustrations of 29 common baby signs.
“Hungry” in sign language
It’s important for baby to be able to communicate when they’re tummy feels empty—you know, before they get hangry. Teach them how to show you they’re “hungry” in sign language. You can make the sign for “hungry” by cupping your hand around your neck to make a C shape, then move your hand down from your neck to your stomach.
“Drink” in sign language
Want to learn how to sign “drink” in sign language? This one involves mimicking the action! Make a C shape with your hand, as if you were holding a cup, then move it to your mouth as if you were drinking from it.
“Milk” in sign language
Wondering how to teach baby sign language? It’s best to start with something baby knows, likes and wants—for example, milk. You can communicate the word “milk” in sign language, by making a fists, then extending your fingers and bringing them back into a fist again.
“Water” in sign language
Teach baby how to request “water” in sign language, and you’ll always know when your little one wants their sippy cup. The sign for “water” is made by extending your three middle fingers so they’re pointing up, with your thumb and pinkie tucked down, and then tapping your index finger to your chin.
My oldest learned some baby sign language at daycare, and watching him get his needs met before he could verbally speak was just so gratifying. I was so appreciative of the teachers who helped him communicate before he could speak because otherwise he could get so agitated. “More” and “all done” became the most regularly used gestures in our home for a while—especially when he was eating something he liked (or didn’t like!). And then when he could say ‘maw,’ and he’d pair it with the gesture—swoon!
“More” in sign language
Do you have trouble knowing if and when baby wants extra spoonfuls of their favorite puree? “More” is another important word for you and baby to learn. To express “more” in sign language, pinch your thumbs and fingers together on both hands, creating two O shapes, then tapping your fingertips together a few times.
“Done” in sign language
When baby is full, they want you to stop shoving that spoon toward their mouth. Teach them to let you know they’re “all done” without fussing by using the ASL sign for “finished.” Start with your hands up, palms facing toward you, and turn them until your palms face out.
“Play” in sign language
When it comes to baby sign language, the sign “play” certainly belongs in your arsenal. To communicate “play” in sign language, clench your fingers to your palms, leaving your thumbs and pinkies extended; then with palms facing you, twist your wrists back and forth.
Don't forget to do some fun signs as well like ball and play. You want to make signing interesting for the baby. I started right away and although she can't sign back, she does recognize milk and all done. (She’s 14 weeks old.)
“Sleep” in sign language
Nobody likes having a fussy, sleep-deprived baby on their hands, so it’s a good idea to practice “sleep” in sign language. Hold your hand over your forehead with your fingers spread apart, then draw your hand down over your face until your fingers and thumb come together to touch your chin. Even babies who resist nap time may whip this one out when they’re especially exhausted.
“Mom” in sign language
Your little one will want to know how to address their favorite people in baby sign language. To sign “mom,” simply spread your fingers apart, then with your pinkie facing forward, tap your thumb to your chin.
“Dad” in sign language
As another one of baby’s favorite people, Dad will want in on the fun too! You can make the sign for “dad” by spreading your fingers apart, then with your pinkie facing forward, tap your thumb to your forehead.
“Poop” in sign language
Everybody does it, so you might as well learn to sign it! If you want to indicate “poop” in sign language, clench both hands into fists and stack them on top of each other, with the thumb of the bottom hand tucked inside the upper fist. Then, pull your bottom hand down from the upper hand, leaving your thumb extended. Next time baby soils their diaper, they’ll let you know—before you even smell it.
“Yes” in sign language
Another easy and important sign to learn is “yes.” Enthusiastically nodding your head is great, but this sign gives baby yet another communication tool. Intuitively, “yes” in sign language looks just like a nodding hand. Make a fist and then, folding at your wrist, bob your fist up and down.
“No” in sign language
Again, shaking your head works, but this sign helps reiterate the point. To express “no” in sign language, extend your thumb, index and middle fingers, then quickly snap them together.
“Food” in sign language
Instead of signing “hungry,” baby may want to ask for “food.” This sign can also mean “eat.” Communicate “food” in sign language by flattening your fingers on top of your thumb and then bringing your fingertips to your mouth.
“Help” in sign language
When learning and teaching baby sign language, be sure to review the sign for “help.” This can be useful to baby in so many different situations; plus, being able to ask for support from a parent or caregiver can help reduce any frustration a baby may feel. If you want to communicate “help” in sign language, simply make a fist with one hand, with the thumb extended, and place it over your other hand, which is extended flat. Then move both hands up together.
“Bath” in sign language
Want to tell baby it’s bath time? Express ‘“bath” in sign language by making two fists, then moving them up and down in front of your chest (as if you were scrubbing yourself clean).
“Book” in sign language
Storytime is the best time! Use your hands to say “book” in sign language; clasp your palms together with your thumbs facing up, then hinge open your hands, keeping your pinkies together (as if you were cracking open a book).
“Medicine” in sign language
The sign for “medicine” is made by placing your middle finger into the palm of your opposite hand and twisting.
“Share” in sign language
To sign “share,” extend one hand flat, with your thumb pointing up. Then, run your other hand back and forth along the top of your extended fingers.
“Sorry” in sign language
Teach baby to show empathy and express feelings before they know how to do it verbally. The sign for “sorry” is made by rubbing a fisted hand in a circle over your chest.
We never formally taught baby sign language, but our son did pick up some while watching Ms. Rachel! His favorite sign remains 'Please!' (rub your hand against your chest in circles). To this day (he's 3 now), he’ll ask for something (typically ice cream) and I will say, 'What do you say?' Then he signs, 'Please!' It's so cute and hard to resist.
“Please” in sign language
Manners matter. Teach baby to ask for things politely from the get-go. To sign “please,” extend your fingers and thumb out, then rub your flattened palm against your chest in circles.
“Thank you” in sign language
Nothing is sweeter than watching your little one express gratitude. And they’ll appreciate it when you show them the same respect and courtesy right back. To sign “thank you,” straighten your thumb and fingers, then bring your fingers to your chin and pull them away.
“You’re welcome” in sign language
The sign for “you’re welcome” is the same as the sign for “thank you”—flatten your hand, bring your fingers to your chin and pull them back.
“I love you” in sign language
This is one sign you’re going to both want to use all the time. To sign “I love you,” extend your thumb, index and pinkie fingers (but keep your ring and middle fingers down). Hold your hand out with the palm facing away and rotate your hand side to side.
“Hurt” in sign language
The baby sign for “hurt” is done by clenching both hands into fists, then extending your index fingers and touching them together.
“Good” in sign language
This versatile sign is a great way to get feedback from baby on what they’re eating. It’s also a way for you to express to baby that they’ve done a good job. You can sign “good” in baby sign language by bringing your dominant hand to your mouth and then placing it on top of your other hand with both palms facing up. You can also use this sign to mean “goodnight.”
“Want” in sign language
In baby sign language, “want” looks like you’re pulling something toward you. You’ll have both hands flat and facing up, then you’ll pull them in and curl your fingers as if you’re holding a ball.
“Open” in sign language
This is a great one for when your kiddo needs a little help. Open in baby sign language looks as if you’re opening a window with your hands. Put both hands together flat out in front of you and bring your hands away from you, spinning them so the palms are now facing in.
“Outside” in sign language
To sign “outside,” have your dominant hand open toward your face, then move it away from you, while closing your hand and bringing your fingertips together.
Here, you can see some of the most common signs, all in one comprehensive baby sign language chart.
I love baby sign language…I will be teaching my little one. I want him to have a way to communicate his needs to me without screaming, pointing and whining. I used to work at a daycare, and we had a baby who was taught baby sign language. Instead of throwing all her food on the floor (like other babies), she would sign "finished" so we knew when she was all done. Her verbal skills developed normally alongside her peers.
Baby sign language is thought to offer a bunch of potential short-term and lasting benefits. Being able to understand what your preverbal baby wants or needs—and allowing baby to express themselves without the use of words—can go a long way in building your relationship. Some of the possible benefits of baby sign language are:
Can baby sign language improve speech development?
Some experts believe baby sign language can offer a head start in language acquisition. In the late 1980s, Linda Acredolo, a University of California, Davis professor, and Susan Goodwyn, a professor at University of Southern California, Stanislaus, found that babies who used baby sign language actually learned verbal skills faster than those who didn’t sign. In a second study, they later checked in on those same children at age 8 and found that the babies who used signs scored higher on IQ tests than the non-signers.
Shira Fogel, a speech pathologist who founded Tiny Talkers, a baby sign language workshop program in Portland, Oregon, became a believer in the benefits of sign language for babies after witnessing her first child’s remarkable progress. Her daughter made her first sign (milk) at 5.5 months, knew more than 100 signs at 12 months and could speak in full sentences by the time she was 18 months old. Even the American Academy of Pediatrics believes baby sign language can help bridge the communication gap and has given it its stamp of approval.
It’s worth noting, though, that not all academics agree that baby sign language offers proven benefits—and the research is mixed. While some studies (including the ones conducted by Acredolo and Goodwyn) have found significant upsides to using sign language for babies, other studies haven’t unearthed any significant or long-term differences between children who learn baby sign language and those who don’t. So in general, the benefits of baby sign are considered theoretical.
And, as Jack Maypole, MD, associate clinical professor of pediatrics at Boston Medical Center, points out, some benefits of baby sign language may be overstated and overpromised by the vast offerings of baby sign products on the market. “While learning baby sign language may help hearing parents and children communicate better, the results won’t necessarily be transformative, so be wary of programs that promise to get your child into Harvard or have their first novel published by nursery school,” Maypole says.
My 15-month-old niece has been learning baby signs since she was 5 months old, and she has about a 10-word sign vocabulary now (milk, more, all done, food, sleep, etc.). My mom loves taking the baby out because there are hardly any tantrums. My niece can explain what she wants/needs without crying most of the time. I am definitely going to try it, at least for those very basic items. And yes, it is adorable to see her sign with her fat little toddler hands.
So you’ve brushed up on the possible benefits of sign language for babies—but what about potential downsides? Since baby can begin to communicate using signs instead of spoken words, many parents wonder—does baby sign language delay speech? Fujimoto says no. If baby is developing at a healthy pace, baby sign just supplements their learning and gives them another way to express themselves. If you think baby might actually have a hearing impairment, don’t just rely on baby sign language as a solution, she adds. Talk to your pediatrician about your concerns and ask about referrals to an audiologist, who can perform the proper hearing tests and assessments.
There’s no hard deadline for when to stop using baby sign language. As baby’s language develops, they’ll naturally gravitate toward using the method that “works best to get their wants and needs met quickly,” White says. Once they start using their words consistently to ask for what they need, you can gradually phase out signing if you wish. “Some parents may wish to carry on signing to support with speech delays or simply as a fun bonding tool. There’s no harm in continuing if you and your child enjoy it,” White adds.
Frequently Asked Questions
Is it okay if baby doesn’t sign back?
It’s completely fine if baby doesn’t sign back right away—they’re still absorbing all the basic signs you’re showing them. “Babies are developing many skills at once: motor skills, cognitive abilities, social-emotional awareness and communication,” White explains. “Every baby develops at their own pace. The key is consistent exposure—keep modeling signs during daily routines, even if your baby isn’t signing back yet.”
Is symbolic gesture the same as baby sign language?
They’re related but not the same, says Katie Sterbenz, cofounder of Wee Talkers, a pediatric speech pathology brand that teaches parents of babies and toddlers how to support their child's language and communication. “But we definitely recommend using both gestures and signs with baby. Gestures are actually really important when it comes to language development,” she adds. “Baby sign is a system of gestures and simple signs that are easier for babies and toddlers to copy and say than words,” Sterbenz says.
Can you start baby sign language too early?
“It’s never too early to start introducing simple signs to baby,” says Carly Tulloch, co-founder of Wee Talkers. “If you have the ability to choose, 6 to 9 months is a really nice time to start, but there’s also not a wrong time to start.”
Can baby sign language demotivate baby to learn to speak?
Rest assured it won’t make your little one lose the motivation to speak verbally! “Babies and toddlers do the best they can with the abilities they have,” says Sterbenz. “Because the movements needed to produce signs are much simpler than the complex fine motor movements required to speak, they usually imitate these signs before spoken words. And when spoken words are just as easy as signs, they’ll do it!”
Don’t look at sign language as a delayant; rather, think of it as a step in the right direction! “When you’re incorporating sign language, always model spoken language with the sign and encourage any and all vocalizations! Even if it doesn’t match up with the word perfectly,” suggests Sterbenz.
Is baby sign language the starting point for ASL?
“ASL is something very different from the type of sign language we’re encouraging you to use with your babies,” explains Tulloch. “ASL is its own language with its own grammatical structure… Baby sign, on the other hand, is used by hearing parents to help their child communicate faster or more effectively.”
Now that you know the basics of how to teach baby sign language, begin practicing a few words you think you’ll use most frequently at home. Your little one will love having a special way to communicate their wants and needs with you. What’s more, having the ability to express your feelings to each other will help strengthen your bond. It’s a win-win!
