A reference table of typical language milestones from birth to around age six. Every child develops at their own pace — these are general patterns, not a checklist to worry over.

Milestone table

Typical language-development stages by age
AgeTypical languageHow reading helps
0–6 monthsCoos, gurgles, reacts to voices and toneHearing your voice and rhythm; simple sound patterns
6–12 monthsBabbling, first sounds like 'mama/dada', responds to nameNaming pictures, repeating sounds, board books
12–18 monthsFirst words; understands more than they sayPoint-and-name books; labelling everyday objects
18–24 monthsVocabulary grows fast; two-word phrasesSimple stories with repetition; asking 'where is…?'
2–3 yearsShort sentences; hundreds of words; many questionsPredictable stories; talking about the pictures
3–4 yearsLonger sentences; tells simple stories; 'why?'Story sequence; asking what happens next
4–5 yearsClear speech; grammar improving; rich vocabularyRicher narratives; new words in context
5–6 yearsComplex sentences; early reading of familiar wordsTaking turns reading; sounding out words

How to support language at every stage

  • Talk through daily routines, narrating what you do.
  • Follow the child's interest and expand on what they say.
  • Read aloud daily and let them fill in familiar words.
  • Sing songs and rhymes — rhythm and repetition help.
  • Give time to answer; resist finishing their sentences.

Frequently asked questions

When should a child say their first word?
Often around 12 months, but a range from about 9–15 months is common. Understanding usually runs ahead of speaking.
Does being bilingual delay language?
Bilingual children may mix languages and reach some milestones slightly differently, but bilingualism does not cause a language disorder. Total vocabulary across both languages is what matters.
