How communication develops in the early years

From the very first cry to chatty little stories, your child is building one of life's great superpowers — connection through communication.

In short

Communication in the early years grows in a steady, predictable arc — long before a child says their first word. It begins with eye contact, cries and smiles, blossoms into babble, gestures like pointing and waving, then single words, two-word combinations and finally little sentences and back-and-forth conversations. Crucially, communication is far bigger than talking — it includes understanding, gesturing, sharing attention and turn-taking, which all develop together through warm, responsive everyday moments with you.

How communication unfolds, step by step

Communication develops along two intertwined threads: understanding (what a child takes in) and expression (what a child sends out) — and the understanding usually runs ahead of the talking.

• Birth–6 months: Your baby communicates through crying, cooing, eye contact and that wonderful first social smile. They turn towards your voice and begin to coo and gurgle back.
• 6–12 months: Babbling appears ("bababa", "dadada"), and your baby starts to respond to their name, follow your gaze, and use early gestures. Joint attention — sharing a moment with you over a toy or a bird outside — is a vital building block here.
• 12–18 months: First true words emerge, alongside pointing, waving and showing you things. Understanding grows quickly — they follow simple instructions like "give me the ball".
• 18–24 months: Vocabulary expands rapidly, and many toddlers begin joining two words together ("more milk", "daddy go").
• 2–3 years: Short sentences arrive, conversations begin to flow, and a child becomes increasingly understandable to familiar listeners.

These windows are guides, not deadlines — children vary, and gesture, eye contact and understanding matter just as much as spoken words.

When a gentle check helps

Most children move through these stages at their own pace, and a little variation is completely normal. It is worth a friendly developmental check if, by around 12 months, there is no babbling, pointing or other gestures; if there are no single words by around 16–18 months; if there are no meaningful two-word phrases by around 2 years; or if at any age your child seems to lose words or social skills they once had, rarely makes eye contact, or does not respond to their name. Early support, when needed, is gentle, play-based and remarkably effective.
