A baby’s first sign typically appears around 8.5 months old, though the range spans from as early as 5.5 months to as late as 12 months. The most commonly learned first sign is “More,” made by tapping the fingertips together repeatedly—a simple gesture that babies can physically manage and that immediately gets results when they want another bite of food, another song, or more playtime. If you’re starting a baby sign language chart, you’ll want to focus on need-based signs like “More,” “Milk,” “Water,” “All Done,” and “Diaper,” along with family member signs like “Mommy” and “Daddy.” These early signs aren’t just cute milestones; they’re a practical communication tool that can reduce frustration during the 6-to-12-month period when babies have thoughts but no words to express them. You can begin introducing signs as early as 6 to 7 months old, though some babies show readiness to watch and respond to signing even at 4 months.
The timeline isn’t rigid—developmental readiness matters more than calendar age. Most babies who’ve been exposed to signing will start signing back somewhere between 10 and 14 months old. For hearing children in deaf households, the advantage is notable: sign-exposed infants typically produce their first signs about 1.5 to 2 months earlier than hearing children produce their first spoken words, simply because the motor control for signing develops slightly ahead of the fine motor control needed for speech articulation. This article walks through what a baby sign language first signs chart should include, the developmental window when babies are ready to learn, which signs to prioritize, and what realistic expectations are for benefits and progress.

When Are Babies Ready to Learn Signs?
Babies don’t wake up at 8.5 months and suddenly sign “More.” There’s a progression of readiness signs that appears months earlier. Around 5 to 7 months, babies begin to sit independently and show early motor control by clapping their hands and raising their arms—these are the first hints that their hands will soon be capable of intentional gestures. By 6 months, babies enter a phase called “manual babbling,” where they make hand movements similar to the vocal babbling they’re doing with their mouth. They’re practicing the motor patterns without yet connecting those patterns to meaning. The first truly meaningful gesture is pointing, which typically appears between 9 and 12 months.
Once a baby can point to show you something they’re interested in, they’ve crossed a cognitive threshold: they understand that a specific hand shape or movement can communicate an idea to another person. This is when signing becomes possible, not just as imitation but as intentional communication. If your baby is younger than 5 months and you’re eager to start, you can begin signing during everyday routines—your baby will absorb the visual input even if they’re not ready to sign back yet. However, if your baby hasn’t yet shown sitting balance or hand awareness, there’s little point in expecting results. Wait for the readiness signs.
The Advantage of Starting Early—And What Early Really Means
One of the most compelling reasons parents choose to teach baby sign language is the documented communication advantage: babies exposed to signing can communicate through signs 2 to 3 months earlier than children who only use spoken language. For a parent dealing with a pre-verbal toddler who’s frustrated because they can’t express their needs, 2 to 3 months feels significant. A 10-month-old who signs “More” and “Milk” and “All Done” is reducing the guessing game around what they want. However, it’s important to temper expectations about long-term benefits.
Research shows mixed evidence for lasting developmental advantages from baby sign programs. Some studies suggest early signing provides a modest communication head start, but other longitudinal research finds that the advantage tends to narrow by age 3 or 4, as spoken language catches up and becomes the dominant mode of communication in hearing households. The real value isn’t typically in permanent IQ or language superiority—it’s in the reduced frustration during those early toddler months when communication is most difficult. If you’re hoping that signing will make your child multilingual or gifted, the research doesn’t support that outcome. But if you’re hoping to reduce meltdowns because your 11-month-old can tell you they want water instead of screaming, signing delivers on that promise.
The Essential First Signs to Teach
Most baby sign language charts start with the same core vocabulary because these signs map to babies’ most pressing needs and are simple enough for developing motor skills. “More” tops nearly every chart because it’s versatile—it works for more food, more play, more anything—and the hand movement is easy for babies to master. “Milk” and “Water” address the primary need that occupies most of a baby’s day. “All Done” gives babies a way to signal that they’ve finished eating, which is information parents actually need. “Diaper” is useful primarily for communication clarity rather than demand, but some families include it.
Beyond the core need-based signs, most charts include family member signs: “Mommy,” “Daddy,” and sometimes “Baby.” Then come early concept signs: “Cat,” “Dog,” “Bath,” “Bed,” “Ball,” “Book,” and “Car.” The theory behind this selection is that these are things babies see frequently and have emotional reactions to—food triggers hunger, bath time is a distinct routine, books are often shared activities, and pets capture a baby’s attention. The limitation of these charts is that they assume your baby has this exact life. If you don’t have a cat or dog, teaching the sign for “Dog” is less useful than teaching a sign for something your baby actually encounters. Customize the chart to your baby’s environment. If your baby spends time at a sibling’s soccer practice, “Ball” makes sense. If your baby has never seen a cat, that sign is just busywork.
Building a Usable First Signs Chart for Your Family
A practical first signs chart should be visual and physical—either printed and posted where you do most of your baby care, or as a laminated card you can carry in your diaper bag. The chart should show the sign itself, the word in written English, and ideally a brief description of the hand movement. “More” means tapping your fingertips together in front of your body; “All Done” means both hands open and wave from your wrists, usually paired with a slight shrug. Without the verbal description, a static image only gets you halfway there. The timing of introducing signs matters.
Rather than trying to teach five signs at once, introduce them in context: teach “Milk” during feeding, “Bath” during bathtime, “All Done” when your baby is actually finished with a meal. This is called “incidental teaching,” and it’s far more effective than flashcard drills with a pre-verbal baby. Your baby learns that the sign coincides with the real-world event they’re experiencing. Most research suggests that teaching 3 to 5 core signs over a period of weeks, then gradually expanding, produces better results than information overload. The tradeoff is patience: your baby will learn signs at their own pace, not because you’ve printed a comprehensive 20-sign chart. A smaller, focused chart that you actually use consistently will teach more signs than an elaborate chart that overwhelms you into abandonment.
Signs Your Baby Isn’t Ready—And When to Troubleshoot
If you’ve been signing “More” for three months and your baby still hasn’t signed it back, the issue is usually developmental, not educational. Some babies simply aren’t motorically ready until closer to 12 or even 14 months. This doesn’t mean your signing is failing; it means your baby’s fine motor control hasn’t caught up. You can continue signing—you’re building receptive understanding even if expressive signing hasn’t started—but expecting results before the 10-month mark may set you up for frustration. Another common problem is inconsistency.
If you sign “Milk” but your partner doesn’t, or if grandparents are unaware and speak without signing, your baby gets a mixed input signal. Babies do better with consistent modeling across caregivers. Before concluding that your baby “doesn’t like signing,” ensure that everyone in your baby’s daily life is on the same page. Similarly, if you’re overwhelmed and signing only sporadically, your baby receives insufficient exposure to build the neural pathways and motor memory. The research suggests that regular, daily exposure to signing produces results; sporadic exposure leaves babies without the consistency they need. If you’re considering sign language but can’t commit to using it daily, the realistic expectation is slower learning or minimal take-up from your baby.
The Deaf Advantage in Early Signing
There’s an important distinction worth understanding: deaf children exposed to sign language from birth begin signing earlier and progress faster than hearing children learning sign as a second language. Deaf infants of deaf parents typically produce their first signs around 6.5 months old, compared to hearing babies who rarely sign before 8 to 10 months. This 1.5 to 2-month advantage isn’t about intelligence or development—it’s about the anatomy of sign production versus speech production. The gross and fine motor control required for clear signing develops slightly earlier than the neurological precision required for intelligible spoken language.
This difference has implications for first signs charts designed for hearing families: a chart that works for deaf families teaching sign as a native language may look different from one for hearing families teaching sign as a supplemental tool. Deaf families might include more complex signs earlier or use a larger initial vocabulary, because the deaf child is literally learning sign as their primary language. Hearing families are typically teaching sign as a communication bridge for the pre-verbal phase, which means the priority is simple, high-frequency signs that reduce frustration. Understanding this distinction helps you set realistic expectations for your own family’s signing journey and avoid comparing your hearing baby’s signing timeline to videos of deaf babies who are on a different developmental track.
The Critical Period and the Long-Term Picture
Developmental psychology emphasizes a “critical period” for language acquisition—the window during which the brain is most primed to absorb and internalize language patterns. For sign language, as for spoken language, early exposure matters. A baby exposed to fluent sign language from birth develops native-like proficiency because their brain is processing it during the critical period. However, this critical period extends over years, not months. The window for optimal language learning begins around birth and remains open through early childhood, with some continued plasticity into late childhood.
The practical takeaway is this: starting signing at 6 months versus 12 months versus 18 months does matter, but it’s not a now-or-never moment at 8.5 months. Your baby’s brain remains capable of learning language through your early toddler years. If you start signing at 18 months, your child can still become fluent—it just may take longer than if you’d started at 6 months. The most important factor isn’t the exact age you start, but that you start with consistency and continue with persistence. Baby sign language isn’t a race to the finish line of a first signs chart; it’s the beginning of a communication tool that can grow with your child.
Conclusion
A baby sign language first signs chart serves a practical purpose: it gives parents a starting framework of 8 to 12 simple, high-value signs that address a baby’s core needs and abilities. The most successful charts are small and focused—”More,” “Milk,” “All Done,” “Water,” family names, and a handful of objects your baby encounters regularly. Starting between 6 and 7 months old allows you to build visual familiarity and model consistent signing during the months before your baby has the motor control to sign back, typically between 10 and 14 months.
The realistic expectation is that consistent early signing will give your baby a communication advantage of 2 to 3 months during the pre-verbal toddler phase—a meaningful window for reducing frustration but not a long-term developmental game-changer. The real value lies in the day-to-day reduced frustration, the shared routine of signed communication with your baby, and the knowledge that your baby has a tool to express themselves before speech arrives. Customize the chart to your baby’s world, remain patient with the timeline, and build signing into your daily caregiving rather than treating it as a separate learning task. Your baby will learn—at their own pace, on their own timeline.
Frequently Asked Questions
Can I start signing with my baby at 3 months?
You can sign around a 3-month-old, and they’ll absorb the visual patterns, but they won’t produce signs back. Babies typically show readiness to sign around 5 to 7 months. There’s no harm in starting early, but don’t expect intentional signing from a very young baby.
How do I know if my baby is ready to learn signs?
Look for developmental readiness signs: your baby sits independently, claps their hands, raises their arms, or shows interest in hand movements. Once your baby begins pointing (typically 9 to 12 months), they’re definitely ready to intentionally produce signs.
What if my baby hears and I don’t know sign language—can I still teach signs?
Yes. You can learn basic signs from videos, apps, or resources like babysignlanguage.com and teach them to your baby. Fluency isn’t required; consistent, daily signing matters more than perfect accuracy. Your baby will learn the basic forms even if your signing isn’t polished.
Will teaching signs delay my baby’s speech?
No. Research does not support the idea that signing delays spoken language development in hearing children. Hearing babies typically continue developing speech on the typical timeline while also learning signs.
Should I teach American Sign Language (ASL) or a simplified “baby sign” system?
Both approaches work, but simplified baby sign is often easier for beginners and focuses on the most useful early signs. If you have a deaf family member or want your child to learn a true language with grammar and depth, ASL is the better choice. For a hearing family seeking pre-speech communication, simplified systems are sufficient.
How many signs should I teach at once?
Start with 3 to 5 core signs—typically “More,” “Milk,” “All Done,” “Water,” and one family name. Introduce them over several weeks in natural contexts rather than all at once. Add new signs gradually as your baby begins to use the first ones.
