Gestures Are Language: Why Your Baby's Pointing Changes Everything

Why Pointing Is the Developmental Milestone You Should Actually Celebrate

We throw parties for first steps and record first words, but pointing rarely gets the recognition it deserves — even though decades of research show it may be the most reliable early predictor of language outcomes. A foundational meta-analysis by Colonnesi and colleagues (2010), which has been extended and confirmed by more recent work, demonstrated a strong relationship between pointing gestures at 12 months and expressive vocabulary at 24 months. More recently, Lucca and Wilbourn (2022) published findings in Developmental Science showing that the quality of pointing — not just whether a child does it, but how they integrate it with vocalizations and eye contact — predicted vocabulary growth trajectories across the second year of life. Children who pointed while simultaneously vocalizing and making eye contact with their caregiver showed the steepest vocabulary growth curves. In other words, pointing is not a simple motor act. It is a package deal that reflects joint attention, social cognition, and communicative intent all working together.

The Three Types of Gestures (and Why Each One Matters)

Not all gestures are created equal, and understanding the categories can help you recognize just how much your child is already "saying" before they speak a single word. Researchers classify early gestures into three main types. Deictic gestures are the heavy hitters — pointing, showing (holding an object up for you to see), and giving (placing an object in your hand). These emerge first and are powerful because they require the child to understand that you have a separate mind and attention. Representational gestures are conventional actions with shared meaning — waving bye-bye, blowing kisses, shaking the head for "no," nodding for "yes." These show that a child can use a symbol (the wave) to stand for a concept (departure). Finally, symbolic gestures are pretend actions — holding a fist to the ear as a "phone," pretending to drink from an empty cup, making a stuffed animal "walk." Each type builds on the last, creating a scaffold from concrete reference ("look at that!") to abstract representation ("this block is a cookie") — the very cognitive leap required for spoken language.

• Deictic gestures (pointing, showing, giving): emerge 9-12 months, reflect joint attention and communicative intent
• Representational gestures (waving, nodding, blowing kisses): emerge 10-14 months, show understanding of social conventions
• Symbolic gestures (pretend actions like talking on a phone): emerge 12-18 months, demonstrate the ability to use symbols — the same cognitive skill needed for words

Gesture-Word Combos: The Bridge to Sentences

Here is where things get truly fascinating. Research by Ozcaliskan, Adamson, and Dimitrova (2021), published in the Journal of Child Language, confirmed that children who produce more gesture-plus-word combinations transition to two-word speech faster than children who rely on gestures or words alone. What does a gesture-plus-word combination look like? A child points at a ball and says "Daddy" — meaning "Daddy, throw the ball." Or they wave and say "bye" — combining the representational gesture with the word. These combinations are the developmental bridge between single words and sentences. The child is expressing a two-concept idea ("Daddy" + "ball") before they have the linguistic capacity to string two words together vocally. Goldin-Meadow's extensive research program, including her 2020 work on gesture-speech mismatches, has shown that when a child's gesture conveys different information than their speech (pointing at a ball while saying "Daddy"), it signals that their cognitive system is ready for the next leap. The mismatch is not confusion — it is the brain rehearsing a more complex idea than the mouth can yet produce. It is readiness in action.

Baby Sign Language: Helpful or Hype?

The baby sign language debate has generated strong opinions on both sides, so let us look at what the current evidence actually says. A systematic review by Fitzpatrick and colleagues (2023), published in the Journal of Speech, Language, and Hearing Research, examined whether teaching signs to hearing infants accelerates spoken language development. The findings were nuanced: teaching baby signs does not appear to give children a long-term advantage in spoken vocabulary once they are talking, but it does provide short-term benefits in reducing frustration, supporting early communication, and strengthening the parent-child communication loop. Critically, baby sign language does not delay spoken language — a concern many parents voice. Signs serve as a bridge, not a replacement. Most children naturally drop signs as spoken words become easier to produce. The key takeaway from current research is this: baby sign language is a wonderful tool if it feels natural and enjoyable for your family, but it is not required. What IS required is responsive communication — and that can happen through gestures, signs, words, facial expressions, or any combination that keeps the back-and-forth going.

• Baby sign language does NOT delay spoken language — this myth has been thoroughly debunked
• Signs can reduce frustration by giving pre-verbal children a way to express needs ("more," "all done," "help")
• The benefit comes from the interaction, not the signs themselves — any gesture system that increases back-and-forth communication helps
• Children naturally phase out signs as spoken words become easier to produce

When to Worry: Absence of Pointing as an Early Red Flag

The updated American Academy of Pediatrics (AAP) developmental surveillance guidelines, reinforced in their 2020 clinical report on early identification of developmental delays, emphasize that absence of pointing by 14 to 16 months is a significant red flag warranting developmental screening. This is not about creating anxiety — most children point well before their first birthday. But pointing is so foundational to communication development that its absence can signal broader difficulties with joint attention, social engagement, or communicative intent. Landa (2018), in her work published in the Journal of Autism and Developmental Disorders, found that reduced gesture use in the first year of life was one of the earliest observable differences in children later diagnosed with autism spectrum disorder. Importantly, this does not mean that every late pointer has autism — far from it. But it does mean that gesture development deserves the same attention we give to walking and talking. If your child is not pointing by 14 months, not using any gestures (waving, reaching with an open hand, shaking their head) by 12 months, or has lost gestures they previously used, contact your pediatrician or request an early intervention evaluation. Early action protects your child's developmental trajectory.

Your Gesture Guide: What to Model at Every Age

The best part about gesture development is that you can actively support it through modeling — and it does not require any special training or equipment. Just your hands, your face, and your attention. During the 9-to-12-month window, focus on pointing at things in your environment constantly. Point at the dog, the airplane, the banana. Exaggerate your point, look where you are pointing, then look back at your child. You are teaching them the magic of shared attention. From 12 to 18 months, layer in representational gestures alongside words: wave and say "bye-bye," nod and say "yes," put your finger to your lips and say "shh." Show them objects and name them. Give them opportunities to give you objects ("Can you give me the ball?"). From 18 to 24 months, start modeling symbolic gestures during pretend play — hold a block to your ear like a phone, pretend to eat a toy apple, make a stuffed animal "sleep." Research by Rowe and Goldin-Meadow (2009), with follow-up work extending into the 2020s, showed that parents who gesture more have children who gesture more — and those children go on to have larger vocabularies at school entry. Your hands are teaching tools. Use them generously.

• 9-12 months: Point at everything, exaggerate your pointing, and look back at your child to build shared attention
• 12-18 months: Wave, nod, shake your head, and show objects — pair every gesture with a word
• 18-24 months: Model pretend actions during play (stir a pot, drink from an empty cup, rock a baby doll) and narrate them
• All ages: Respond enthusiastically to every gesture your child produces — this teaches them that communication works
