The loss of previously gained skills is the key early sign and warrants prompt medical assessment, not home diagnosis.","answer_md":"*Many baby girls grow beautifully for months — then a parent senses something has quietly shifted, and trusting that instinct matters.*\n\n## In short\nRett Syndrome typically follows a distinctive pattern: a girl develops normally for roughly the first 6–18 months, then growth of head size slows and previously gained skills — like purposeful hand use, babble or words — gradually fade. The most telling early sign is the loss of purposeful hand movements, replaced by repetitive hand-wringing, washing or mouthing motions. These are signs to observe and bring to a clinician promptly, not to diagnose at home — Rett Syndrome is a genetic condition that benefits from early, coordinated medical and therapy support.\n\n## Early signs to watch\n**A period of typical development first**\n- Usually grows and develops as expected for the first 6–18 months\n- Then a slowing or stalling, sometimes a quiet regression\n\n**Head growth slows**\n- Head circumference, normal at birth, grows more slowly between about 5 months and 4 years (acquired microcephaly)\n\n**Loss of purposeful hand skills**\n- Previously used hands — reaching, grasping, holding a toy — are gradually lost\n- Replaced by repetitive hand movements: wringing, squeezing, clapping, tapping or bringing hands to the mouth\n\n**Communication and social changes**\n- Loss of babble or first words; reduced eye contact or social engagement that may later return\n- Sometimes mistaken for autism in this early phase\n\n**Movement and other signs**\n- Trouble with walking or unsteady, wide-based gait; stiffness\n- Slowed overall growth; teeth-grinding; breathing irregularities (breath-holding or rapid breathing) when awake\n\nWhat distinguishes Rett is the **sequence** — a settled early period, then a slowing and loss of hand skills and communication. Because it is a recognised genetic condition (most often linked to the MECP2 gene), any suspected regression deserves a prompt medical review.\n\n## When to seek a check — promptly\nIf your daughter loses skills she once had — especially purposeful hand use, babble or words — or if her head growth seems to be slowing, see a paediatrician or developmental specialist soon. Loss of previously gained milestones is always a reason for prompt medical assessment, and genetic testing can confirm the diagnosis. Early support does not change the genetics, but it meaningfully supports comfort, communication, mobility and family wellbeing.\n\n## The Pinnacle way\nAt [Pinnacle Blooms Network](/rett-syndrome), we walk beside families through every stage — protecting communication, movement and dignity with a coordinated, strengths-first plan. Support such as [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) helps with hand function, daily skills and sensory comfort, while communication is nurtured through alternative and assistive routes. 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; nothing here is a diagnosis. Across 70+ centres in 4 states and 4.95 lakh+ families served, our aim is steady, compassionate progress.\n\n## Trusted sources\nAligned with WHO ICD-11 (LD90.0), and developmental and child-health guidance from the American Academy of Pediatrics and HealthyChildren.org on milestones and developmental regression.\n\n**Next step —** if your daughter has lost skills she once had, or you've noticed unusual hand movements, book a developmental review with our clinical team on WhatsApp at +91 91001 81181, and let's understand her together.\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","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","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-rett-syndrome-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Early Signs of Rett Syndrome | Pinnacle","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Keep a simple month-by-month note or short videos of milestones your daughter reaches — reaching, holding toys, babble, first words.
