Speech Delay in Children
“Is my child talking enough for their age?”
Children develop communication skills at different rates, but there are expected developmental milestones that can help parents recognise when further assessment may be useful.
It is also important to distinguish expressive language from receptive language:
- Expressive language = what your child can say or communicate
- Receptive language = what your child can understand
A child may have difficulty with one, the other, or both.
Typical Speech & Language Milestones
Milestones are approximate — children do not all develop at exactly the same age.
When Should Parents Be Concerned?
Seek Medical Care If:
- Your child is not meeting expected communication milestones.
- Your child is not using single meaningful words by around 18 months.
- Your 2-year-old is not combining words meaningfully.
- Your child's speech is very difficult to understand for their age.
- Your child does not seem to understand simple instructions.
- Your child does not point, gesture or share interests.
- Your child does not respond consistently to their name.
- There are concerns about social interaction or play.
- Your child loses words or communication skills they previously had.
These concerns do not automatically mean autism or another diagnosis. They are reasons to look more closely at the child's overall development.
Speech Delay ≠ Autism
A child can have an isolated speech or language delay and otherwise develop typically.
However, when speech delay occurs together with difficulties in:
- Eye contact and social interaction
- Responding to name
- Pointing or sharing interests
- Pretend play
- Back-and-forth interaction
- Repetitive behaviours or restricted interests
An assessment for Autism Spectrum Disorder (ASD) may be appropriate.
The DSM-5-TR diagnosis of autism requires difficulties in social communication/social interaction together with restricted or repetitive behaviours. Speech delay alone does not diagnose autism.
“What About Screen Time?”
Language develops through interaction.
Talking, reading, singing, playing and having back-and-forth interactions provide opportunities for children to learn communication.
Excessive passive screen exposure may displace these important interactions. Therefore, for young children, prioritise:
Talking + Reading + Playing + Face-to-face interaction
rather than relying on videos or apps to teach speech.
“Don't Forget Hearing”
Hearing is an important part of speech and language development.
A child may appear to hear normally but still have hearing difficulties that affect speech development. Hearing assessment should be considered when there is significant speech or language concern.
“Early Assessment Does Not Mean Labelling”
Some children with late language development will catch up.
But “wait and see” should not mean “do nothing.”
Early assessment can identify hearing problems, developmental differences or communication difficulties and allows appropriate support to start early — even before a final diagnosis is established.
What to Expect During the Consultation
The paediatrician will review developmental milestones, hearing history, play, social communication and medical factors. Hearing assessment and referral to a speech and language therapist, occupational therapist or developmental specialist may be recommended. Early intervention programmes (EIP) can be useful even before a final diagnosis is established.
