What every parent should know about Blue Book checks, speech milestones, and a new Medicare pathway that could help your family.
Before your baby ever says "mum" or "dad," they're already communicating — through cries, coos, eye contact, and those first gummy smiles. These early skills are the building blocks for everything that comes after: talking, learning, and connecting with the people around them.
That's why we don't wait until toddlerhood to start paying attention. It starts from birth.
What's a Blue Book check, again?
Every child born in NSW gets a Blue Book — a Personal Health Record that tracks growth, immunisations, and development from birth to school. It also maps out eight recommended check-ups:
1–4 weeks → 6–8 weeks → 6 months → 12 months → 18 months → 2 years → 3 years → 4 years
At Paddington Doctors, your GP and our nursing team, including a dedicated Child and Family Health Nurse, run these checks together, covering everything from growth and hearing to behaviour and communication.
Bring the Blue Book to every visit and don't wait for the "next scheduled check" if something feels off. If your child seems to have lost a skill, or a milestone isn't landing, come see us sooner.
Talking isn't the only sign of progress
It's easy to focus purely on word count, but communication has three separate parts, and a good check looks at all of them:
Receptive language — what your child understands, such as following directions, recognising names and answering questions.
Expressive language — how they communicate through gestures, sounds, words and sentences.
Speech — how clearly they produce sounds and words.
A child can understand tons but struggle to get words out. Or say plenty of words but miss the meaning of a question. Each piece matters on its own.
Why 18 months is a big one
The 18-month check is a key moment for language. By this age, most kids are:
- Attempting at least 3 words beyond "mum" or "dad"
- Following a simple one-step instruction without gestures or hints, such as handing over a toy when asked
One missed milestone isn't a diagnosis, these checklists are a guide, not a pass/fail test. But a pattern of missed milestones, a lost skill, or a parent's gut feeling is always worth raising.
What comes next: 2, 3 and 4 years
By age 2, most children:
- Combine two words, such as "more milk"
- Point to named objects or body parts
- Use a wider range of gestures
By age 3, most children:
- Hold short back-and-forth conversations
- Answer "who," "what," "where" and "why" questions
- Describe what's happening in a picture
By age 4, most children:
- Speak in sentences of four or more words
- Recall parts of songs or rhymes
- Talk about their day and answer questions about everyday objects
Every child's path looks a little different, the overall pattern over time matters more than any single tick-box.
When to consider a speech pathology referral
It's worth raising with your GP or nurse if your child:
- Isn't responding consistently to sounds or their name
- Has very limited babbling, pointing or gestures
- Struggles to understand simple words or directions
- Uses very few words, or isn't combining words yet
- Is hard to understand, even for family
- Gets frustrated trying to communicate
- Repeats sounds, gets "stuck," or shows signs of stuttering
- Has lost a skill they previously had
A speech pathologist can assess all of it; understanding, expression, speech sounds, fluency and social communication, and help determine whether your child needs a little more time, some monitoring or additional support.
At Paddington Doctors, we have an established referral pathway with KidsSpot, a local paediatric allied health service in Rose Bay thay we work closely with. When speech or language concerns are identified, your GP can discuss whether a speech pathology referral to KidsSpot may be appropriate and help make that next step a little easier. Having a trusted pathway in place also helps support continuity between your child's GP and the clinicians involved in their ongoing care.
A new Medicare pathway worth knowing about
Since 1 March 2026, the Medicare M10 pathway has expanded to cover:
- Stuttering
- Speech sound disorders, including apraxia and dysarthria
- Cleft lip and/or palate
For eligible kids and young people under 25, this can mean rebates for up to 8 assessment services and up to 20 treatment services — though these are lifetime limits, not annual ones, and treatment referrals are capped at 10 services each, so two referrals are needed for the full 20.
A few important caveats:
- It's a rebate, not free care, the current rebate is $87.25, and providers can charge above that if they don't bulk bill.
- For assessment, a suspected condition is enough for referral. For treatment, a confirmed diagnosis is required first.
- General language delays, such as difficulties with understanding, vocabulary or combining words, aren't automatically covered by M10 on their own, but that doesn't mean support isn't available. We can talk you through public speech pathology services, other Medicare items, private options and more.
Getting the most from your check
A few minutes of prep goes a long way. Before your appointment, jot down:
- What words, sounds or gestures your child currently uses
- What they seem to understand
- Whether strangers can understand their speech
- Any frustration around communicating
- Anything childcare or preschool has flagged
- Any skills they've stopped using
A quick video of them playing or chatting at home can be genuinely useful too , kids don't always perform on cue in a clinic room.
The bottom line
Blue Book checks aren't just about weight and immunisation, they're regular chances to catch things early, ask questions and get support before small concerns become bigger ones. Whether it's the 18-month check or the 4-year check, every visit is a chance to make sure your child's communication is on track.
