A first-step tool
The checklist helps you move from a vague “I am not sure” feeling to a few concrete observations. It can be a starting point for noticing progress, deciding what to watch over time, and preparing a conversation with a pediatrician, audiologist, or speech-language pathologist.
Scan common communication patterns from later infancy through the preschool years.
Check only what you actually notice in daily life. Leave unknowns blank instead of testing or pressuring.
Use the notes area for specific examples, changes, context, and questions you may want to raise.
What is inside
The PDF is a compact reference, not a complete developmental assessment. It covers speech, language, gestures, listening, and broader communication in a simplified way.
6–9 months
Back-and-forth sounds, squeals, repeated babbling, name response, and gestures for connection.
1 year–18 months
Waving, understanding familiar words, first word attempts, pointing, showing, and one-step directions.
2 years
Two-word combinations, named pictures and body parts, and a wider range of gestures.
30 months–3 years
Growing vocabulary, action-word combinations, questions, names, and back-and-forth conversation.
4 years
Four-word sentences, songs and stories, talking about the day, and answering simple questions.
5 years
Stories with connected events, conversation across several exchanges, story questions, and rhymes.
Use it today

Keep the PDF where you can return to it instead of trying to remember every item.
