YOUR QUESTION. A CLEARER NEXT STEP.
When to worry about prematurity-related developmental risk at two
For a child born premature, milestones at two are best judged from their corrected age — their due date, not their birth date — until around age two. Prematurity-related developmental risk doesn't mean something is wrong; it means we watch progress closely. A check is warranted if there's a clear, persistent lag across areas even after correcting for age, or any loss of skills already gained.

If your little one arrived early and you're watching their second birthday wondering whether they're catching up, your attentiveness is exactly the right instinct.
In short
For a child born premature, the right question at two isn't "are they behind?" but "are they progressing steadily from their corrected age?" Prematurity-related developmental risk simply means your child started earlier than expected, so we measure milestones from their due date — not their birth date — until around age two. Worry is warranted not because of prematurity itself, but if your child shows a clear, persistent lag across areas even after correcting for age, or loses skills they once had. A gentle developmental check brings clarity sooner than waiting ever does.
What to watch at two — corrected age first
First, do the maths: if your child was born 10 weeks early, a 24-month-old is developmentally closer to about 21–22 months. Judge them against that. Watching with that lens, a developmental check is sensible if, around their corrected two-year mark, your child:
- Communication — uses very few or no single words, doesn't combine two words, or rarely responds to their name or simple instructions.
- Social & play — shows little eye contact, shared smiling, pointing to show you things, or pretend play.
- Movement — isn't yet walking steadily, or strongly favours one hand/side (which can hint at an underlying motor pattern).
- Overall trajectory — has stopped gaining skills, or has lost words, gestures or steadiness they clearly had before.
Many children born early are simply on a slightly later but perfectly healthy curve and catch up beautifully by school age. The point of checking is not to label — it's to make sure that any area needing a little support gets it during these high-opportunity early years, when the developing brain responds best.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online list or a single moment. Our clinicians always correct for prematurity, map your child's own strengths and emerging skills, and — if early communication is the worry — our speech therapy team can begin gentle, play-based support. The goal is a clear picture and a confident way forward.

Next step — Trust what you've noticed. Book a developmental assessment with a Pinnacle clinician so your child's progress is reviewed using their corrected age and their own strengths.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Judge milestones from your child's corrected age (their due date), not birth date. Seek a check if, around their corrected two-year mark, they use very few words, don't combine two words, show little pointing or pretend play, aren't walking steadily, or have lost skills they once had.
In everyday life
Write your child's adjusted age on a sticky note — birth date minus how many weeks early they arrived. Use that number, not their actual age, when checking any milestone chart this year. It often turns needless worry into well-earned reassurance.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
How do I work out my child's corrected age?
Take your child's actual age and subtract the number of weeks they were born early. If your two-year-old arrived 10 weeks early, their corrected age is roughly 21–22 months — and that's the age to use when checking milestones, generally until about two years.
Will my premature child always be behind?
Most children born preterm catch up by school age, especially with corrected age applied in the early years. Prematurity-related developmental risk means we watch progress closely, not that a delay is inevitable. A clinician can map your child's own trajectory.
Is two years old too early to assess a premature child?
Not at all. Two is an excellent time for a gentle developmental check, because the early years are when support works best. A Pinnacle clinician will always correct for prematurity and focus on your child's strengths, never just a label.
