Teaching ASL to kids works best when you start with a handful of practical signs, pair them with spoken words, and weave them into everyday routines your child already knows. Babies as young as 6 months can begin producing their first signs, and by age 2, many children string signs together into simple phrases like “more cookie” or “no juice.” Whether your child is deaf, hard of hearing, or a hearing baby who simply isn’t talking yet, the approach follows the same core principles.
Why Start With Sign Language
Signing gives young children a way to communicate before their mouths and vocal cords are ready for speech. Research from Northwestern University found that even 3- and 4-month-old hearing infants gained a cognitive advantage in forming object categories when exposed to ASL, mirroring the benefits of hearing spoken language. Importantly, the advantage came specifically from the linguistic elements of ASL, not from pointing and gesturing alone.
For hearing children, signing bridges the gap between understanding language and being able to speak it. A toddler who can sign “milk” or “all done” has far fewer reasons to scream at the dinner table. For deaf and hard-of-hearing children, early ASL exposure lays the foundation for full language development on the same timeline as their hearing peers.
First Signs to Teach
Start with signs your child will use dozens of times a day. The most practical first signs center on basic needs and social interactions:
- More: Fingertips of both hands tap together in front of the chest. This is one of the earliest and most motivating signs because it gives your child immediate power to ask for what they want.
- Eat: Fingertips tap the lips, as if putting food in your mouth.
- Milk: Open and close your fist, like squeezing a cow’s udder.
- All done: Both hands open, palms facing you, then flip outward with a small wave.
- Sleep: Open hand slides down the face as the eyes close.
- Play: Both hands in a “Y” shape (thumb and pinky extended), twist at the wrist.
- Drink: Mime tipping a cup toward your mouth.
- Thank you: Flat hand touches the chin, then moves forward and down.
Some signs are physically easier for small hands than others. Signs like “eat,” “milk,” and “more” use simpler hand shapes that babies can approximate early. Signs like “help,” “cookie,” and “cracker” involve more complex finger positions and typically come later. Don’t worry if your child’s version of a sign looks messy at first. Just like babbled words, approximations count.
How to Teach Signs Effectively
The most reliable technique is pairing a sign with the spoken word during a natural moment. When you’re asking your toddler if they want more food, say “Do you want mooooore?” while holding the sign for “more” right where they can see it. The elongated speech, the repetition, and the visual sign all reinforce the same concept at once. This isn’t a formal lesson. It’s just narrating life with your hands as well as your voice.
Repetition matters more than variety. Introduce two or three signs at a time and use them consistently for a week or two before adding new ones. Sign in context: use “eat” at mealtimes, “sleep” at bedtime, “play” when you’re heading to the toy bin. Children learn language by mapping words to real experiences, and signs work the same way.
Songs and books create natural opportunities for practice. If your child loves “The Itsy-Bitsy Spider,” learn the signs for “spider,” “rain,” and “sun” and layer them into the song. Picture books let you sign what’s on each page while you read. These routines are predictable, which helps kids anticipate and eventually produce the signs themselves.
Signing With Babies vs. Toddlers
Between 6 and 12 months, babies begin babbling with their hands and can start producing single signs. At this stage, you’re mostly modeling. Sign consistently and celebrate any attempt your baby makes, even if it only vaguely resembles the target sign. Between 1 and 2 years, children start combining signs into two-word phrases: “more cookie,” “mommy book,” “no juice.” This mirrors the same milestone in spoken language and signals that your child is building grammar, not just memorizing gestures.
Baby Sign vs. Actual ASL
There’s an important distinction between using a few ASL signs with your baby and actually teaching ASL as a language. Many “baby sign” programs borrow individual ASL signs but strip away the grammar, sentence structure, and facial expressions that make ASL a complete language. Without those elements, you’re using symbolic gestures, not signing ASL.
This matters for two reasons. First, if your child is deaf or hard of hearing, they need full ASL with its syntax, facial grammar, and directional rules, not simplified gestures. Signs like “give” and “mine/yours” rely on directionality: where your hands move in space changes who is giving and who is receiving. The sign for “hungry” becomes a question by raising your eyebrows, leaning forward, and signing “hungry? you? hungry?” That eyebrow raise isn’t decoration. It’s ASL grammar.
Second, it’s a matter of cultural respect. ASL is the primary language of the American Deaf community, and referring to borrowed gestures as “a language” without the grammar and pragmatics of ASL is culturally inappropriate. If you’re a hearing family borrowing signs to bridge a communication gap with a hearing baby, that’s a valid and helpful tool. Just be clear about what you’re doing and what you’re not.
Eye Contact and Facial Expression
If you’re teaching real ASL rather than a handful of baby signs, facial expression and body language are not optional extras. They carry grammatical meaning. A statement and a question can use the exact same hand signs, with raised eyebrows being the only difference. Deaf signers also read extremely subtle facial and body movements, so developing this skill early gives children a significant advantage.
Eye contact rules in ASL differ from spoken English norms. In a signed conversation, the listener must watch the signer continuously. Breaking eye contact signals disinterest or rudeness. Teaching your child to maintain eye contact while someone signs builds both language comprehension and cultural fluency. In practice, this means getting down to your child’s eye level when you sign, making sure they’re looking at your face and hands rather than something across the room.
When to Expect Results
Most parents start signing to their babies around 6 months and see the first recognizable sign back somewhere between 8 and 12 months. That timeline varies widely. Some babies sign back within weeks, while others take several months of consistent exposure before producing anything. The receptive understanding (your child responding correctly to a sign) almost always comes before the production (your child making the sign themselves).
By 12 to 14 months, many signing children have a handful of reliable signs. By 18 to 24 months, children who have been exposed consistently often combine signs into short phrases. For hearing children, this signing ability typically coexists with emerging speech rather than replacing it. Many parents notice that signed words eventually drop away as spoken words become easier for the child to produce.
Resources for Learning ASL as a Family
Learning alongside your child is essential, especially if no one in the household already signs. Several reputable organizations offer structured materials designed specifically for families:
- ASL University: A free online curriculum covering vocabulary and grammar, useful for parents who want to move beyond baby signs into real ASL.
- VL2 Storybook Apps: Developed by Gallaudet University’s Visual Language Visual Learning Center, these interactive apps present stories in both ASL and English.
- Bravo Family ASL Course: Streaming video lessons that teach vocabulary, grammar, and Deaf culture through real-world scenarios. Available through the Described and Captioned Media Program.
- ASL Deafined: A subscription-based video lesson platform designed for all ages, including parents of deaf children.
- Dawn Sign Press and Boys Town Press: Publishers offering ASL books and media for both adults and children.
Local Deaf community events, ASL meetups, and classes taught by Deaf instructors are the single best way to develop real fluency. No app fully replaces learning from a person who uses ASL as their primary language. Many communities offer family-friendly ASL classes specifically for parents of young children, and these also connect you with the cultural context that makes the language meaningful.
