First, when your toddler vocalizes or attempts sounds, responding with words back to them matters enormously. That back-and-forth is the strongest driver of vocabulary growth. Second, everyday narration works: describing what you're both doing (\"You're stacking blocks!\") and celebrating their attempts builds their word bank faster than any structured program. Third, repetition counts—both repeating words your toddler knows and using varied action words (run, jump, climb instead of just \"go\") helps them build richer language. If your toddler isn't getting much verbal response to their attempts, or if your family's conversations are limited, adding more of those moments could make a real difference over the next few months.\n\nIf you're concerned about whether their development is on track beyond vocabulary alone, it's worth checking in with your pediatrician—but in terms of boosting words, responsive conversation and natural narration are your strongest tools.","sources":"[{\"pmid\":\"31045301\",\"title\":\"Infants' intentionally communicative vocalizations elicit responses from caregivers and are the best predictors of the transition to language: A longitudinal investigation of infants' vocalizations, g\",\"journal\":\"Developmental science\",\"year\":\"2020\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/31045301/\",\"score\":0.79},{\"pmid\":\"31030872\",\"title\":\"Infant Language Production and Parenting Skills: A Randomized Controlled Trial.\",\"journal\":\"Behavior therapy\",\"year\":\"2019\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/31030872/\",\"score\":0.78},{\"pmid\":\"26300377\",\"title\":\"Input and uptake at 7 months predicts toddler vocabulary: the role of child-directed speech and infant processing skills in language development.\",\"journal\":\"Journal of child language\",\"year\":\"2016\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/26300377/\",\"score\":0.77},{\"pmid\":\"26638832\",\"title\":\"Diversity matters: parent input predicts toddler verb production.\",\"journal\":\"Journal of child language\",\"year\":\"2017\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/26638832/\",\"score\":0.77}]","thread_json":null,"topic":"toddler-milestones","view_count":0,"created_at":"2026-08-28T08:01:16.430Z"}
