If undiagnosed, the signs are mainly developmental — later walking, softer muscle tone, slower speech — plus features sometimes noted in infancy. No list confirms it; a calm developmental check with a paediatrician is the right next step, and early therapy helps greatly.","answer_md":"*By two, you already know your son better than any checklist — but if a quiet worry keeps returning, it deserves a gentle, clear answer rather than a search bar at midnight.*\n\n## In short\nDown syndrome is almost always recognised at or soon after birth, so by age two most families already have a diagnosis confirmed by a blood test (karyotype). If your son has *not* been formally diagnosed and you are noticing a pattern, the signs at this age are usually about development and a few physical features — and the right next step is a calm, unhurried developmental check, not a self-diagnosis. Down syndrome is something a child is born with; it is not caused by anything you did.\n\n## What this can look like at two\n**Developmental pattern (most common reason for a second look)**\n- Walking later than peers, or moving with a softer, floppier muscle tone (hypotonia)\n- Fewer words than expected, or speech that is slower to come and harder to understand\n- Taking longer to learn new play and self-help skills, fairly evenly across areas\n\n**Physical features sometimes seen** (these vary a great deal, and many typically developing children share one or two)\n- Smaller stature, a flatter facial profile, upward-slanting eyes, a single deep crease across the palm\n- A history of feeding or heart concerns noted in infancy\n\n**Important:** no single feature confirms or rules out Down syndrome. It is confirmed only by a genetic (chromosome) test arranged by a doctor — never by appearance or by a list like this.\n\n## When to have it checked\nIf your son is markedly behind on walking or first words, or if a clinician noticed features in infancy that were never followed up, book a developmental review with your paediatrician. This is reassuring whatever the outcome: either it settles your worry, or it opens the door to early therapy — and for children with Down syndrome, [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate), physiotherapy and play-based support started early make a real, lifelong difference to communication, mobility and independence.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online list.
