Early Signs of Developmental Language Disorder at 12–18 Months

At 12 to 18 months, language is just beginning to bloom — so how do you know whether to simply keep watching, or to seek a gentle check?

In short

At 12–18 months, Developmental Language Disorder (DLD) is not yet diagnosed, because there is wide, healthy variation in when toddlers say their first words. What you can do is watch a few early communication milestones — responding to their name, understanding simple words, pointing, babbling and gesturing. If several of these are noticeably behind, it is worth a developmental check; these are signs to observe and discuss, never to diagnose at home.

Early communication signs to watch (12–18 months)

A formal DLD label is usually considered only from around 4 years, once language has had time to develop. Before then, we watch the building blocks of communication:

Understanding (receptive)

• Does not seem to respond to their own name by around 12 months
• Does not appear to understand simple familiar words like "milk", "bye-bye" or "no"
• Cannot follow a very simple instruction with a gesture (e.g. "give me" with hand out)

Talking and sounds (expressive)

• Little or no babbling with varied sounds ("bababa", "dadada") by 12 months
• No clear first words by around 15–18 months
• Babble that does not grow towards word-like sounds

Gestures and social communication

• Not pointing to show or ask for things by 16–18 months
• Few gestures such as waving, reaching up to be held, or shaking head
• Limited eye contact paired with sounds, or little back-and-forth "conversation" of babble and looks

A late first word on its own is common and often catches up. What matters more is a cluster of these — especially weak understanding and few gestures — and whether it persists as your child grows.

When to seek a check

Because early language varies so widely, the wise stance at this age is watch-and-monitor with a low threshold to ask. Book a developmental screen if your toddler shows several of the signs above, if babble or gestures have stopped, or if your instinct simply says something feels different. Early communication delays can also link with hearing, so a hearing check is often a sensible first step too.
