Assessment & diagnosis
Can Down Syndrome be diagnosed in a 12-to-18-month-old?
Down syndrome is a genetic condition present from birth and is confirmed by a chromosome (karyotype) blood test, not by milestones or behaviour. At 12–18 months it can certainly still be confirmed with that test if it was not identified earlier; delays alone do not diagnose it but are a reason to ask your paediatrician for a review. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.
Read the answer AnswerCan Down Syndrome Be Diagnosed in a 3-to-6-Month-Old?
Yes — Down syndrome can be identified at 3 to 6 months, and is usually recognised at birth or during pregnancy because it is a genetic condition present from conception. It is confirmed by a karyotype blood test that counts chromosomes, not by watching development. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.
Read the answer AnswerCan Down Syndrome Be Diagnosed in a 6-to-9-Month-Old?
Yes — Down syndrome can be diagnosed in a 6-to-9-month-old, though it is usually identified much earlier, before or at birth. It is confirmed by a karyotype (chromosome) blood test, which is definitive at any age, not by observing behaviour. By 6–9 months a diagnosis is rarely uncertain, so the focus shifts to early developmental support. Only a qualified clinician can confirm a diagnosis through proper testing.
Read the answer AnswerCan Down Syndrome Be Diagnosed in a 9-to-12-Month-Old?
Yes — Down syndrome can be diagnosed at 9–12 months, and usually it is recognised at or before birth. It is a genetic condition confirmed by a simple blood test (karyotype), not by watching behaviour. At this age the focus shifts to early, loving support for movement, communication and play. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.
Read the answer AnswerCan Down Syndrome Be Diagnosed in a Newborn?
Yes — Down syndrome can often be suspected at birth from a baby's physical features and is confirmed with a karyotype (chromosome) blood test, which gives a clear answer in a few days. Prenatal screening may also have indicated it before birth. A diagnosis is the start of a supportive journey: early nurturing care helps every baby thrive, and a clinical AbilityScore® is formed only at a Pinnacle Blooms Network centre under qualified clinician care.

My 12–18 Month Old May Be Showing Signs of Down Syndrome — What Should I Do?
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.
Read the answer AnswerMy 3-to-6-month-old is showing signs of Down syndrome — what should I do?
If you suspect Down syndrome in your 3-to-6-month-old, the right step is a prompt paediatric visit — it is confirmed by a blood test (karyotype), not by looks. Present from birth, it is recognised early, and early support for the heart, hearing, vision and movement, plus play-based therapy, helps your baby thrive from these very months.

If you notice possible signs of Down syndrome in your 6–9-month-old, see your paediatrician promptly for a genetic (karyotype) blood test that confirms or rules it out — appearance alone cannot. Down syndrome is present from birth, so a clinical check now gives a clear answer. Begin early developmental support either way, and arrange the routine heart, hearing, vision and thyroid checks. Many children with Down syndrome grow, learn and thrive with early help.
Read the answer AnswerSigns of Down syndrome at 9-12 months: what to do
Down syndrome is present from birth and confirmed only by a karyotype blood test, not by observation. If you notice signs at 9–12 months, see your paediatrician promptly for examination and testing, plus early heart, hearing and vision checks. Whatever the result, early developmental support at this age genuinely helps your baby thrive.
Read the answer AnswerNewborn Signs of Down Syndrome — What Should I Do?
If your newborn shows possible signs of Down syndrome, ask your paediatrician for a karyotype blood test, which is the only way to confirm it. Once confirmed, arrange recommended newborn checks (heart, hearing, vision, thyroid, feeding) and begin gentle early intervention. Children with Down syndrome learn, play and thrive with warm, early, strength-based support.
