Down syndrome is usually recognised at or soon after birth from a pattern of physical features — low muscle tone, a flatter facial profile, upward-slanting eyes, a single palmar crease — confirmed by a simple karyotype blood test. No single feature confirms it, and early checks plus loving support help children thrive.

*When you first hold your newborn, the questions can feel big — but recognising the early signs of Down syndrome is the gentle first step towards the right support, early.*

## In short
Down syndrome is usually recognised at or soon after birth from a recognisable pattern of physical features, often confirmed by a simple blood (karyotype) test. The common newborn signs include low muscle tone, a flatter facial profile, upward-slanting eyes and a single crease across the palm. These are gentle physical markers — not a measure of your child's future, which loving, early support shapes enormously.

## Early signs you may notice
**At or soon after birth**
- Low muscle tone (hypotonia) — baby feels softer or 'floppier' when held
- A flatter facial profile and a small nose with a flat bridge
- Eyes that slant slightly upwards, sometimes with small skin folds at the inner corner
- A single deep crease across one or both palms (single palmar crease)
- A shorter neck, smaller ears, and a gap between the first and second toes
- A protruding tongue and a smaller mouth

**In early months**
- Feeding may take a little longer because of low tone
- Motor milestones — head control, rolling, sitting — often arrive a bit later

No single feature confirms Down syndrome, and many babies share one or two of these. A blood test (karyotype) gives the clear answer.

## Why this matters early
[Down syndrome](/down-syndrome) (ICD-11 LD40.0) arises from an extra copy of chromosome 21. Recognising it early opens doors to important checks — heart, hearing, thyroid and vision — and to early developmental support that builds communication, movement and learning from the very start. Children with Down syndrome learn, play, attend school and thrive; early, joined-up support simply helps them flourish sooner.

## The Pinnacle way
At Pinnacle Blooms Network, your child's strengths are mapped through a clinician-administered structured assessment, and Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — never from an online list. From there we plan [special education](/special-education) and therapy around your child. Learn how the [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) gives an objective, multi-domain baseline. Across 70+ centres in 4 states, our 700+ therapists walk this path with 4.95 lakh+ families.

## Trusted sources
Guided by WHO ICD-11 (LD40.0), CDC 'Learn the Signs. Act Early.', the Indian Academy of Pediatrics, and the American Academy of Pediatrics via HealthyChildren.org.

**Next step —** speak to your paediatrician about a karyotype test if you notice these signs, and reach the Pinnacle team on WhatsApp +91 91001 81181 to plan early developmental support.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
