Baby Sign Language Guide

Baby sign language lets your little one communicate before they can talk. Using simple hand gestures based on American Sign Language (ASL), babies as young as 6 to 8 months can tell you what they want, how they feel, and what they see - dramatically reducing frustration for both of you.

Key takeaways

  • Babies can start learning signs between 6 and 8 months and typically sign back around 8 to 10 months after consistent exposure.
  • Research shows signing does not delay speech -- signing babies often speak sooner and develop larger vocabularies.
  • Start with 3 to 5 high-motivation signs like 'milk,' 'more,' and 'all done,' then add more as your baby masters them.
  • Signing reduces frustration, strengthens the parent-baby bond, and builds early cognitive and fine motor skills.

Why Teach Baby Sign Language?

Gives babies a way to express needs before they can speak, reducing frustration and tantrums

Research shows signing babies often speak sooner and develop larger vocabularies

Strengthens the parent-baby bond through shared communication and understanding

Builds early cognitive skills including memory, visual attention, and symbolic thinking

Encourages early literacy - signing babies tend to show more interest in books

Helps babies develop fine motor skills through purposeful hand and finger movements

When to Start

Most babies are ready to begin learning signs between 6 and 8 months of age. At this stage, they have developed enough fine motor control to start imitating simple hand movements and have the cognitive ability to connect a gesture with its meaning. You can start modeling signs earlier - as young as 4 months - but expect your baby to sign back around 8 to 10 months after consistent exposure.

How to Teach Baby Sign Language

1

Start with 3-5 signs

Begin with the most motivating signs for your baby. 'More,' 'all done,' and 'milk' are great starters because they connect to things your baby already wants. Once your baby uses these consistently, add new signs one or two at a time.

2

Say the word while you sign

Always pair the sign with the spoken word. Baby sign language is a bridge to verbal communication, not a replacement. Speaking and signing together gives your baby two pathways to understand and eventually express the same concept.

3

Use signs in context

Sign 'milk' when you are about to nurse or prepare a bottle. Sign 'dog' when you see a dog. Context is what makes a sign meaningful to your baby. Avoid drilling signs out of context like flashcards - real-life moments are the best classroom.

4

Be patient and consistent

Most babies need to see a sign dozens of times before they use it themselves. The typical timeline is 2-3 months of consistent modeling before your baby signs back. Keep signing even when it feels like nothing is happening - your baby is absorbing more than you realize.

5

Watch for approximations

Your baby's first signs will not look perfect. A baby signing 'more' might just clap their hands together loosely instead of tapping fingertips. These approximations count as real communication. Respond enthusiastically to show your baby that signing works.

6

Get the whole family involved

Babies learn faster when everyone around them uses the same signs. Teach your partner, grandparents, siblings, and daycare providers the signs you are using. Consistency across caregivers accelerates learning.

30 Signs to Teach Your Baby

Start with a few signs from the Essentials category and add more as your baby masters them. Each sign includes the recommended starting age and step-by-step instructions.

Essentials

More

6-8 months

Bring all your fingertips together on each hand to form two pinched shapes, then tap them together in front of your chest. Repeat the tapping motion two or three times.

Tip: This is often the first sign babies learn. Use it at every meal and during play when your baby wants to continue an activity.

All Done

6-8 months

Hold both hands up in front of you with palms facing outward, then twist them back and forth at the wrist, as if waving goodbye with both hands at the same time.

Tip: Pair this sign with mealtime routines. When your baby pushes food away or turns their head, model the sign and say 'all done' out loud.

Milk

6-8 months

Extend your hand in front of you and open and close your fist repeatedly, as if you are squeezing a cow's udder. The motion should be gentle and rhythmic.

Tip: Use this sign right before and during nursing or bottle feeding so your baby connects the sign to the experience.

Eat

6-8 months

Bring your fingertips together into a pinched shape and tap them against your lips several times, as if you are putting food into your mouth.

Drink

6-9 months

Cup your hand as if holding an imaginary cup, then tilt it toward your mouth as if taking a sip. Repeat the tipping motion a couple of times.

Help

8-10 months

Make a fist with one hand and place it on top of the open palm of your other hand. Raise both hands together upward, as if the open hand is lifting the fist.

Tip: This is a valuable sign for reducing frustration. When your baby struggles with a toy or task, model the sign before stepping in.

Please

10-12 months

Place your open hand flat against your chest and rub it in a circular motion. Keep the movement slow and gentle.

Tip: Introduce this sign once your baby has a few other signs mastered. It teaches early manners in a natural, pressure-free way.

Food & Drink

Water

8-10 months

Make a W shape by holding up your three middle fingers (index, middle, and ring finger) and tap them against your chin two or three times.

Banana

8-10 months

Point your index finger upward on one hand to represent the banana, then use your other hand to make a peeling motion down the length of the finger, as if peeling a real banana.

Tip: This sign is easy for babies to learn because the peeling motion is fun and memorable. Use it whenever you offer banana slices.

Cracker

8-10 months

Make a fist with one hand and tap it against the elbow of your other arm, as if you are cracking something. Repeat two or three times.

Cheese

9-12 months

Press both palms together flat, then twist them back and forth against each other as if pressing cheese in a cheese press.

Apple

9-12 months

Make a fist with your hand and press the knuckle of your index finger against your cheek. Twist your fist back and forth as if twisting the stem of an apple.

Feelings

Happy

8-10 months

Place your open hand flat against your chest and brush it upward and outward in a circular motion, as if joy is bubbling up from your heart. Repeat two times with a smile.

Tip: Always pair this sign with a big, genuine smile. Your facial expression is just as important as the hand movement.

Sad

8-10 months

Hold both open hands in front of your face with fingers spread, then drag them downward slowly, like tears falling down your cheeks. Make a sad facial expression as you sign.

Tip: Label your baby's emotions with this sign: 'You look sad. Are you sad?' This builds emotional vocabulary early.

Hurt

9-12 months

Point both index fingers toward each other and twist them back and forth in opposite directions in front of your body, as if something is twisting painfully.

Tip: This is one of the most important signs for safety. A baby who can tell you they hurt can help you locate the source of pain.

Tired

9-12 months

Hold both hands open with fingers spread in front of your chest, palms facing your body. Let both hands slowly drop and droop downward, while also drooping your shoulders and head slightly.

Scared

10-12 months

Hold both fists in front of your chest and quickly open them while pulling your hands apart, as if something startled you. Widen your eyes and make a surprised expression.

Love

8-10 months

Cross both arms over your chest in a self-hug, hands resting on opposite shoulders. Squeeze gently, as if hugging yourself or someone you love.

Tip: Use this sign freely and often. Signing 'I love you' before naps and bedtime creates a comforting ritual.

Animals

Dog

8-10 months

Pat your thigh with your open hand a couple of times, as if calling a dog to come, then snap your fingers once. Babies often just do the patting motion.

Tip: If you have a pet dog, this sign comes naturally. Point to the dog, sign 'dog,' and say the word. Real-life context is the best teacher.

Cat

8-10 months

Pinch your thumb and index finger together near the side of your cheek and draw them outward, as if tracing a cat's whisker. Repeat on one or both sides.

Bird

8-10 months

Hold your index finger and thumb together near your mouth and open and close them like a bird's beak pecking or chirping. Keep the motion small and quick.

Tip: Use this sign when you hear birds singing outside or see them at the park. Signing in real-world contexts helps babies connect signs to meaning.

Fish

9-12 months

Hold one hand flat in front of you with fingers together, palm facing sideways. Wiggle the hand side to side, imitating a fish swimming through water.

Bear

10-12 months

Cross both arms over your chest and make scratching or clawing motions with your fingers against your shoulders, like a bear scratching itself.

Bunny

10-12 months

Hold up two fingers (index and middle) behind your head like bunny ears, then bend and straighten them together a few times, imitating a rabbit's ears twitching.

Tip: This is a fun sign that babies enjoy making. Use it with stuffed animals, picture books, or when you spot a rabbit outside.

Activities

Play

8-10 months

Extend your thumb and pinky finger on both hands (hang-loose shape) and twist both wrists back and forth at the same time, with a playful expression.

Book

8-10 months

Place both palms together in front of you as if praying, then open them outward like a book opening, keeping the pinky edges together as the spine.

Tip: Sign this before reading time. Babies who sign 'book' when they want to be read to are showing early literacy interest.

Bath

8-10 months

Make two fists and rub them up and down on your chest in a scrubbing motion, as if washing yourself in the tub.

Sleep

8-10 months

Hold one open hand in front of your face with fingers spread, then slowly draw the fingers together as you bring your hand downward, closing your eyes at the same time.

Tip: Use this sign as part of your bedtime routine. Signing 'sleep' along with other cues like dimming lights helps baby anticipate rest time.

Outside

9-12 months

Hold one hand open with fingers together in front of you like a door, then pull it outward toward you in a grasping motion, as if reaching outside through a doorway. Repeat twice.

Music

9-12 months

Hold one arm out horizontally in front of you and wave your other hand back and forth above it, as if conducting an orchestra or keeping time to music.

Tip: Babies respond naturally to music. Sign this when you start singing or turn on a song, and your baby will soon request music on their own.

Frequently asked questions

When should I start teaching my baby sign language?
Most babies are ready to begin learning signs between 6 and 8 months. You can start modeling signs as early as 4 months, but expect your baby to sign back around 8 to 10 months after consistent exposure.
Does baby sign language delay speech?
No. Research by Acredolo and Goodwyn shows that signing babies often speak sooner and develop larger vocabularies. Signing is a bridge to spoken language, not a replacement.
How many signs should I start with?
Start with 3 to 5 high-motivation signs like 'milk,' 'more,' 'all done,' 'eat,' and 'help.' Add more signs gradually as your baby masters the initial ones.
What if my baby makes the sign incorrectly?
Baby approximations are completely normal and expected. Just as babies babble before speaking clearly, they will modify signs to match their motor abilities. Respond to their attempt enthusiastically and continue modeling the correct form.
Will my baby stop signing once they start talking?
Yes, most babies naturally transition from signing to speaking as their verbal skills develop, typically between 18 and 24 months. Some may continue to use signs alongside speech for emphasis or clarity.

Bottom line

Baby sign language is a safe, evidence-based way to help your baby communicate before they can talk. Research consistently shows that signing does not delay speech -- in fact, signing babies often develop larger vocabularies and speak sooner. Starting with a few simple signs around 6 to 8 months can reduce frustration and strengthen your bond.

Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
