When to worry about Developmental Language Disorder at age 2

If your two-year-old is saying far fewer words than other toddlers their age, it's natural to wonder — and asking early is a loving, sensible thing to do.

In short

At two, there's a wide and normal range of talking. As a gentle guide, by 24 months most toddlers use around 50 words and are starting to join two together ("more milk", "daddy go"). Developmental Language Disorder (ICD-11 6A01.2) is a persistent difficulty understanding or using language that isn't explained by hearing loss or another condition — but at this age it isn't usually labelled, because language is still emerging. The right step now is observe-and-check, not worry. These are signs to bring to a clinician, never a self-diagnosis.

Signs worth a gentle check at two

Consider a developmental and hearing check if you notice several of these, especially together:

• Very few spoken words — well under ~50 by 24 months, or not yet combining two words by 24–30 months
• Not seeming to understand simple everyday instructions ("get your shoes", "give it to daddy")
• Little use of gesture — not pointing, waving or shaking head to communicate
• Lost words — said some words, then stopped using them
• Little interest in communicating — not trying to share, request or show you things

One quiet patch on its own is rarely a worry — toddlers vary hugely, and many "late talkers" catch up. It's a persistent pattern, or a child who seems to struggle to understand as well as speak, that deserves a closer look. Always rule out hearing first: even glue ear from frequent colds can mute early language.

When to refer

Book a check sooner rather than later if: very few words and little understanding by 24 months; no two-word phrases by around 30 months; loss of words already learned; or if your gut says something isn't right. Early support shapes the brain when it is most ready — there is everything to gain and nothing to lose by checking.
