The Critical 16: An Updated Checklist Of Gestures Your Toddler Should Master By 16 Months

Every parent knows the excitement of a baby's first word, but the true foundation of communication is built long before speech emerges. As of today, December 26, 2025, the most critical and up-to-date milestone for early communication development is the "16 Gestures by 16 Months" checklist, a key metric established by leading researchers at the First Words Project. Missing this benchmark can be a significant indicator that a child may face a language delay, making it essential for parents and caregivers to track these non-verbal cues.

This comprehensive milestone serves as a powerful predictor of future linguistic ability. Research has consistently shown that the number of gestures a child uses between 9 and 16 months is strongly correlated with their language skills two years later. Understanding and actively encouraging these specific communicative actions is one of the most proactive steps you can take to boost your toddler's cognitive and verbal development.

The Complete 16 Gestures by 16 Months: A Developmental Checklist

The 16 Gestures by 16 Months milestone is not just a random count; it represents a child’s progress from simple actions to complex symbolic communication. Children should be adding approximately two new gestures each month between nine and sixteen months. These gestures are broadly categorized into two types: Proto-Imperative (gestures used to request or demand something, like pointing to a cookie) and Proto-Declarative (gestures used to comment or share interest, like pointing to a plane in the sky). Both types are vital for robust language acquisition.

Here is the consolidated, critical list of gestures, categorized by the approximate age they typically emerge:

Gestures Emerging Around 9-10 Months (Early Communicative Intent)

  • 1. Give: Offering an object to a parent or caregiver. This shows a basic understanding of sharing and social interaction.
  • 2. Shake Head: Shaking the head side-to-side to indicate "No" or refusal. This is a foundational proto-imperative gesture.
  • 3. Reach: Extending arms or hands toward a desired object or person, a clear proto-imperative request.
  • 4. Raise Arms: Lifting arms up to signal "Pick me up." This is a key social and proto-imperative gesture.

Gestures Emerging Around 11-12 Months (Shifting to Social Sharing)

  • 5. Show: Holding up an object to draw another person's attention to it, without necessarily giving it away. This is an early proto-declarative action.
  • 6. Wave: Opening and closing the hand to say "Hello" or "Goodbye." This is a crucial social routine gesture.
  • 7. Open-Hand Point (or Tap): Using the whole hand or a tap to draw attention to an object or picture. This is often a precursor to the index finger point.
  • 8. Clap: Bringing hands together to express enjoyment, praise, or excitement. This is a symbolic gesture that is often imitated.

Gestures Emerging Around 13-14 Months (Symbolic and Representational Gestures)

  • 9. Index Finger Point (Declarative): Using a single finger to point at something interesting (like a bird or a light) simply to share attention. This is a highly significant proto-declarative gesture and a major language predictor.
  • 10. Blow a Kiss: A social gesture, often learned through imitation, that shows a developing understanding of symbolic social routines.
  • 11. Head Nod: Moving the head up and down to signal "Yes" or agreement.
  • 12. Shrug: Raising shoulders, often with palms up, to indicate "I don't know" or "Where is it?" This is a complex symbolic gesture.

Gestures Emerging Around 15-16 Months (Advanced Symbolic and Social Gestures)

  • 13. Shush ('Shhh'): Placing a finger over the mouth to signal quiet. This is a complex, culturally learned symbolic gesture.
  • 14. High Five: Slapping hands with another person for celebration or greeting. This shows advanced social reciprocity.
  • 15. Thumbs Up: Using the thumb to signal approval or agreement.
  • 16. Hand Up ('Stop' or 'Wait'): Using a flat hand held up to communicate a request to pause or stop an action.

The Profound Significance of the "16 by 16" Milestone

Why are these 16 gestures so critical? The answer lies in the deep connection between non-verbal communication and the neural pathways for spoken language. The use of gestures is a bridge from a child's thoughts to their first words.

Gesture as a Language Predictor: The most compelling reason to track this milestone is its predictive power. Research has repeatedly demonstrated that children who meet the "16 by 16" milestone are significantly less likely to experience language delays later on. For instance, the consistent use of a proto-declarative point (pointing to share interest) is one of the strongest predictors of a child's subsequent spoken vocabulary and sentence complexity.

Intentional Communication: Every gesture on this list represents intentional communication. When a child points to a toy (proto-imperative) or points at the moon (proto-declarative), they are demonstrating the understanding that they can influence another person's attention or action. This joint attention—the shared focus between the child, the object, and the caregiver—is a necessary precursor for word learning.

The Link to Symbolic Thought: Symbolic gestures, like waving or blowing a kiss, are early forms of symbolic thought. They are arbitrary motions that stand for a bigger concept (greeting, affection). This same cognitive skill is required to understand that the sound "ball" stands for a round, bouncy object. Mastering the symbolic gestures on the checklist essentially primes the brain for mastering spoken words.

Practical Strategies to Encourage Gesture Development

If your child is approaching 16 months and has not mastered many of these gestures, there are simple, powerful techniques you can incorporate into your daily routine to encourage their development. The key is consistent modeling and reinforcement.

Model and Imitate

  • Be a Mirror: When your child makes any attempt at a gesture—even a partial wave or a clumsy point—immediately imitate them and add a simple, clear word. For example, if they lift their arms, you lift yours and say, "Up! You want up!" This validates their communication attempt and pairs the gesture with the word.
  • Model Repeatedly: Use the target gestures frequently and naturally throughout the day. When you leave the room, dramatically wave and say "Bye-bye!" When you give them a snack, model the "Give" gesture back to them. Repetition in play and routine is how children learn.

Facilitate Joint Attention

  • Narrate the Point: When you want your child to look at something, get close to them, point with your index finger, and excitedly say, "Look! A doggy!" Then, immediately look back at your child to ensure they are sharing your focus (joint attention). This teaches them the power and meaning of the declarative point.
  • Wait and Anticipate: During play, pause before giving your child a desired item (like a toy or a snack). Look at them expectantly. This creates a communicative pressure that encourages them to use a gesture (like a reach or a point) to request the item, making it a proto-imperative success.

When to Seek Professional Guidance

The "16 Gestures by 16 Months" is a crucial screening tool. While every child develops at their own pace, significant lags in the acquisition of these gestures should prompt a conversation with a pediatrician or a speech-language pathologist (SLP).

Red Flags to Watch For:

  • A child at 12 months who does not use at least four gestures.
  • A child at 16 months who uses fewer than 16 gestures.
  • A child who does not use an index finger point (either declarative or imperative) by 16 months.
  • A noticeable regression or loss of previously learned gestures.

Early intervention is key to ensuring the best outcomes for language development. If you have concerns, consulting with an SLP can provide you with personalized strategies and determine if your child needs support to build the foundational communication skills required for talking and learning.
