Down syndrome is usually identified at or soon after birth and confirmed by a karyotype blood test, so by 12–18 months a diagnosis is typically known or not, rather than newly appearing. If you are unsure about features you notice, book a calm paediatric developmental review. Routine heart, hearing and vision checks plus early strengths-based therapy help your toddler thrive at their own pace.

*When you notice something different about how your little one is growing, the bravest and kindest thing you can do is simply ask — and you are already doing it.*

## In short
Down syndrome is usually recognised at or very soon after birth, often confirmed by a blood test (karyotype) — so by 12–18 months your child most likely either has a confirmed diagnosis or has not, rather than something that suddenly "appears". If you are seeing features you are unsure about, the right next step is a gentle paediatric review with a developmental check, not worry alone. Whatever the answer, early support helps your toddler reach their fullest potential — and many warm, full lives begin exactly here.

## What is actually appropriate at 12–18 months
At this age, rather than searching for "signs", it helps to watch your child's everyday development and share anything that feels different with your paediatrician:
- **Movement** — sitting steadily, pulling to stand, beginning to cruise or walk; lower muscle tone (a "floppy" feel) is something a doctor can assess.
- **Communication** — babbling, responding to their name, simple gestures like waving or pointing.
- **Feeding and growth** — how feeding is going and steady weight gain along their own curve.
- **Connection** — eye contact, smiling back, enjoying simple to-and-fro play.

If Down syndrome was suspected at birth, a simple **karyotype blood test** confirms it. If it has not been raised before, your paediatrician can examine your child and decide whether any test or referral is helpful. Either way, this is a calm, planned conversation — not an emergency.

## What helps most, starting now
For children with Down syndrome, early developmental support makes a real, lasting difference. A heart check and hearing and vision reviews are routinely advised, because these can quietly affect development. Beyond that, gentle therapy to build movement, communication and play skills helps your toddler grow into their strengths at their own pace.
