Any loss of previously gained skills is always a reason for a prompt developmental check; only a clinician can confirm.","answer_md":"*Many babies with Rett syndrome seem to develop typically at first — which is exactly why a gentle, watchful eye in the early months matters so much.*\n\n## In short\nRett syndrome often begins with a quiet, healthy-seeming start, followed by a slowing or stalling of development between about 6 and 18 months. The most telling early signs are a loss of skills a baby once had — especially purposeful hand use — together with repetitive hand movements and slowing head growth. These signs deserve a prompt developmental check; only a clinician can confirm what they mean.\n\n## Early signs to notice\n**A change after an early settled start**\n- Slowing of development, or a plateau, after months of seemingly typical progress\n- Loss of skills the baby had — reaching, grasping, babbling or social engagement\n\n**Hand use and movement**\n- Losing purposeful hand use — no longer holding toys or reaching as before\n- Repetitive hand movements once purposeful use fades — wringing, washing-like, mouthing or clapping motions\n- Reduced muscle tone (a \"floppy\" feel) or unsteady, wobbly movements\n\n**Growth and engagement**\n- Head growth slowing relative to the body over the early months\n- Reduced eye contact or social interest, sometimes mistaken for autism early on\n- Feeding difficulties, irritability, or disturbed sleep\n\n## When to seek a check\nAny loss of skills a child once had — at any age — is always a reason to seek a developmental review promptly, rather than waiting. Because [Rett syndrome](/rett-syndrome) involves regression, early review matters even when a baby seemed perfectly well before. Ask your paediatrician for a developmental assessment, and begin supportive [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) input in parallel while answers are sought.\n\n## The Pinnacle way\nAt Pinnacle Blooms Network we map each child's strengths across every developmental domain to build a clear, supportive baseline. A 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 qualified clinician care — never from an online list. Backed by 25 million+ therapy sessions and 4.95 lakh+ families served across 70+ centres, our team walks beside you at every step.\n\n## Trusted sources\nInformed by WHO ICD-11 (LD90.0 Rett syndrome), and developmental-surveillance guidance from the CDC, the American Academy of Pediatrics and NICE.\n\n**Next step —** if your child has lost a skill or you notice these patterns, book a developmental check with Pinnacle on WhatsApp: +91 91001 81181.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-rett-syndrome-in-young-children","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-rett-syndrome-in-young-children","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-rett-syndrome-in-young-children-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Early Signs of Rett Syndrome in Children","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Keep a simple month-by-month note of what your baby can do — reaching, holding toys, babbling.
