How to Supercharge Your Toddler's Vocabulary Growth with Fun and Creativity

For toddlers, learning language is arguably their most important developmental milestone. Not only does it bring your family closer together, but it also bridges their sensory development with their cognitive growth. Language serves as the foundation for how children learn all the complex lessons they need as they grow.

Most toddlers learn language as if they were soaking it up like a sponge. During this critical period, their rapidly developing brains create and recreate so many neural connections with remarkable fluidity. Simply by hearing us use words, our toddlers begin to associate the words and sounds they hear with objects and actions. For a typically developing toddler, this journey progresses from their first words around 9-12 months to an impressive vocabulary of 200-300 words by their second birthday. Language development is also one of the most visible and closely monitored indicators of overall development. When this process does not go as expected, pediatricians are watching closely to identify potential language delays or disorders early. Early detection enables timely interventions, which are crucial for achieving the best outcomes.

Even when language development follows a typical trajectory, intentional and active efforts from parents can significantly influence a child’s progress. Research consistently shows that the more words children hear, the faster their language skills develop and the better prepared they are for school. Importantly, the source of these words matters. Spoken language from caregivers and people in the child’s environment has a far greater impact than words heard from screens or devices.

A strategy I like to discuss with parents comes from the world of improv: “Yes, and…” Early in my career, I encountered a fascinating concept involving improv techniques to support individuals with Alzheimer’s. Professional improv actors Karen Stobbe and Mondy Carter discovered that applying improv principles with their parents who had Alzheimer’s led to profound benefits. Their parents experienced fewer symptoms of anxiety and depression, and the approach also helped the caregivers feel more connected and balanced during challenging times.

For toddlers, while the circumstances are wildly different, applying a similar “Yes, and…” approach can be transformative for language development. As toddlers begin to use words, responding by expanding on what they say accelerates vocabulary growth and enhances their receptive and expressive language skills. For example, when your toddler says, “Ball!” (or more likely, “Ba!”), you can respond with “Red ball!” or “Big ball!” This expands the neural pathways they are forming, promoting more complex language development. When an older toddler exclaims, “Fun!” and you respond with, “How exciting!” you’re building on their expression and enriching their understanding.

This approach also nurtures confidence. By avoiding negative responses like “No” when they use an incorrect word and instead offering gentle corrections, you encourage them to keep trying. For instance, if your toddler calls a dog a “cat,” you might say, “That dog does look like a cat! LIke a big, happy cat!.” Positive reinforcement helps them learn without fear of making mistakes.
