Late Talker or Speech Delay? A Sydney Parent's Guide
How to tell the difference between a late talker who'll catch up and a delay that needs support — milestones by age, red flags, and what helps in the meantime.

"He'll talk when he's ready." Every parent of a quiet toddler has heard it, and often it turns out to be true. Some children really are late bloomers. The problem is that "wait and see" only works out for the children who were always going to catch up, and there's no reliable way to know in advance which ones they are.
At Square One Therapy Hub in Kogarah, our paediatric speech pathologists work with families across the St George area and Sutherland Shire on exactly this question: what's typical, what isn't, and what's worth doing now.
Typical speech and language milestones
Milestones are averages, not deadlines. Use them as a rough guide rather than a test.
- 12 months — first words (mum, dad, ball), responds to their own name, points and uses gestures, babbles with varied sounds
- 18 months — around 20 words, follows simple one-step instructions, points to body parts or familiar objects when named
- 2 years — 50 or more words, starting to combine two words ("more milk", "daddy go"), understands far more than they say
- 3 years — short sentences, asks questions, familiar adults understand most of what they say and strangers understand roughly three-quarters
- 4 years — tells simple stories about their day, speech is largely intelligible to anyone
- 5 years — complex sentences, answers "why" and "how" questions, holds a back-and-forth conversation
Late talker or delay? What the distinction means
A late talker is a child with a small spoken vocabulary who is otherwise developing typically. They understand what's said to them, use gestures freely, play imaginatively, and clearly want to communicate. The words are just slow to arrive.
A speech or language delay involves more than a word count. It might include difficulty understanding language, few or no gestures, limited or repetitive play, trouble with the sounds themselves, or reduced interest in interacting.
The distinction matters because understanding — what speech pathologists call receptive language — is the strongest single indicator. A two-year-old with 20 words who follows instructions, points to things, and brings you a book is in a very different position from a two-year-old with 20 words who doesn't respond to their name.
Most late talkers do catch up. A minority don't, and for those children the time spent waiting is when intervention helps most. That's why we suggest assessing early: if the assessment says no action is needed, that's a good outcome too, and a common one.
Red flags worth an assessment now
- No babbling with varied sounds by 12 months
- No words by 18 months
- Fewer than 50 words, or no two-word combinations, by 2 years
- Regression: losing words or skills they previously had. This warrants prompt review, including with your GP
- Little interest in communicating, or not responding to their name
- No pointing or gesturing to share interest
- Strangers can't understand your three-year-old at all
- Your own persistent sense that something isn't right
Get hearing checked first
Before anything else, have your child's hearing tested, even if they passed the newborn screen. Middle ear fluid ("glue ear") after repeated ear infections is common in toddlers, often has no obvious symptoms, and can affect speech and language development while it's there. It's easy to check for, and it changes the plan if it's present.
What about bilingual households?
Growing up with more than one language does not cause speech delay. Bilingual children may have a slightly smaller vocabulary in each language early on, but their total vocabulary across both is similar to other children, and they hit the key milestones on the same timeline. Mixing languages within a sentence is normal and not a sign of confusion.
Keep speaking your home language with your child, and speak it naturally. A parent talking fluently in their strongest language gives a child far more language input than the same parent speaking hesitantly in English.
What helps while you're waiting
Whether or not you go on to book an assessment, these strategies are well supported and cost nothing:
- Narrate what's happening. Commentary during nappy changes, cooking and the walk to the shops gives your child steady, relaxed language input.
- Expand rather than correct. If your child says "car", reply "yes, a big red car". You're showing the next step up without putting them on the spot.
- Ask fewer questions. Quizzing ("what's this? what colour?") creates pressure. Comments invite conversation better than questions do.
- Wait longer than feels natural. Count to five in your head after you say something. Many children need more processing time than adults instinctively allow.
- Get face to face and follow their lead. Talk about what your child is already looking at, not what you'd like them to look at.
- Read the same books again and again. Repetition is how vocabulary sticks. Let them fill in the ending of a familiar line.
- Turn off background noise. Television and music running constantly make it harder for children to pick out speech.
What happens at an assessment
An initial speech pathology assessment usually runs 45–60 minutes and looks like play. We use a mix of parent interview, observation and standardised measures to build a picture across four areas: understanding, expressive language, speech sound production, and social communication and play.
You'll get a clear explanation in plain language, and we'll tell you honestly whether therapy is recommended and, if so, what the goals and likely timeframe are. If your child is best served by monitoring rather than therapy, we'll say so.
Our page on speech and language delay covers what ongoing support looks like, and we've written separately about how speech therapy supports social skills.
Funding and booking
We work with self-managed and plan-managed NDIS participants (more on NDIS funding here), Medicare Chronic Disease Management referrals, private health extras claimed on the spot via HICAPS, and private clients. No referral is needed to book privately.
We're at 4 Short Street, Kogarah, close to Kogarah station and easy to reach from Hurstville, Rockdale, Carlton, Ramsgate and the Sutherland Shire. Book an assessment or get in touch with a question first.
