Speech and language milestones look different for every child, but there are a handful of consistent signals that tend to matter most. Recognising them early — and knowing when to seek an assessment — can make a meaningful difference to how quickly a child catches up.
1. Limited Babbling by 12 Months
Babbling is the foundation of spoken language. If a baby is not experimenting with a range of sounds by their first birthday, it is worth mentioning at their next check-up rather than waiting to see if it resolves on its own.
2. Few or No Words by 18 Months
Most toddlers have a small but growing vocabulary by 18 months. A child who is not attempting any recognisable words by this stage may benefit from a speech and language screening.
3. Difficulty Combining Words by Age 2
Two-word combinations, like "more milk" or "go park", usually appear around this age. Persistent single-word speech beyond this point is one of the more common reasons families are referred for a full evaluation.
4. Trouble Being Understood by Familiar Adults
Some unclear speech is expected in early childhood, but if even parents and caregivers struggle to understand a child most of the time past age 3, an assessment can clarify whether extra support is needed.
5. Frustration Around Communication
Frequent frustration, tantrums linked to not being understood, or a child who avoids trying to speak are all worth discussing with a speech-language professional — frustration is often the clearest sign a child feels the gap themselves.
None of these signs alone confirm a delay, and every child develops differently. What matters is noticing a pattern and getting a professional opinion early — early intervention consistently leads to stronger outcomes than a wait-and-see approach.
