Milestones · 4-year-olds
Is my 4-year-old's speech where it should be?
At four, your child has roughly a year before formal school. This is the window where speech and language concerns become harder to ignore — and most providers have year-long waitlists. Here's what's typical, what isn't, and what to do if you're worried.
What to expect at 4-year-olds
- 1,000+ words; full sentences with most grammar in place
- Can retell a short story or describe what happened at preschool
- Asks "why?" and "how?" questions
- Most consonant sounds in place except /r/, /th/, and some blends
- Strangers understand ~90%+ of speech
- Uses past tense ("I goed" / "I went"), plurals, pronouns
Red flags worth checking
- Strangers can understand less than 80% of speech
- Sentences are short or grammatically immature ("him goed there")
- Can't follow a 3-step instruction
- Avoids talking with peers, struggles to make friends
- Stutters, repeats syllables, or blocks regularly when speaking
- Can't tell you a simple story about their day
If you're worried — what to do
- If you're hearing sounds like "wabbit" for rabbit or "thumb" instead of thumb (lisp), wait. These are typical at 4 — /r/ and /th/ aren't expected until age 5–7.
- If you're hearing missing sounds (no /s/ at all, no /k/), or sentences that are noticeably immature, book an assessment now. Kindy is six months away and the runway for therapy gets tight.
- Notice **stuttering**. Some disfluency at 3–4 is normal as language explodes. But if it lasts more than 6 months, has secondary behaviours (eye blinking, body tension), or runs in the family, see a speech pathologist now. Early intervention for stuttering has the best evidence base of any childhood speech intervention.
- Get a hearing check before any speech assessment. Glue ear at 4 is common and easy to miss.
The kindy runway
Four is when the question changes from "is my child a late talker?" to "is my child going to be ready for kindy?" Different question, different urgency.
The skills schools watch for in the first six months of formal schooling:
- Following a multi-step instruction without re-prompting
- Retelling a story (a key reading-comprehension precursor)
- Phonological awareness — rhyming, breaking words into sounds, identifying the first sound of a word
- Speech that classmates can understand
- Asking for help when needed
These are language skills, not academic skills, and they're the strongest predictor of how well a child reads in Year 1. A speech pathologist can assess all of them in a single hour-long session.
Stuttering: the time-sensitive one
Most children who start stuttering at 2–3 will stop on their own within a year. The 15–20% who don't develop a chronic stutter — and the best evidence for treatment is before age 6, with the Lidcombe Program (Australian-developed, world-leading).
Signs your 4-year-old's stutter should be assessed now, not later:
- It's been going for more than 6 months
- They're aware of it (avoiding words, getting frustrated)
- A first-degree relative also stutters
- Visible struggle — tension, eye blinking, head movement when stuck
Lidcombe is parent-delivered with weekly speech-pathologist coaching. We deliver it online; works equally well as in-person according to the published trials.
