Any regression warrants prompt paediatric review; only a clinician can assess and confirm.","answer_md":"*Many parents first notice that a happy, developing baby girl seems to pause — and then change. Knowing the early pattern of Rett syndrome helps you act with calm clarity, not fear.*\n\n## In short\nRett syndrome typically shows a distinctive pattern in girls: a period of seemingly normal early development (usually 6–18 months), followed by a slowing or loss of skills, loss of purposeful hand use, and the appearance of repetitive hand movements such as wringing, washing or mouthing. If you notice your daughter losing skills she once had — especially hand skills or babble — share this with a paediatrician promptly. Only a qualified clinician can assess and confirm anything.\n\n## Early signs to notice\n**The early pattern**\n- A stretch of apparently typical development in the first 6–18 months\n- A slowing down, then a loss, of skills the child had already gained\n\n**Hand changes (a hallmark)**\n- Loss of purposeful hand use — no longer reaching, grasping or holding as before\n- Repetitive hand movements: wringing, washing, clapping, tapping or hand-to-mouth\n\n**Communication and social changes**\n- Reduced babble, eye contact or social engagement, sometimes after it had been present\n- Eye gaze may later become a strong way she communicates\n\n**Movement and growth**\n- Unsteady or wide-based walking, or difficulty walking\n- Slowing of head growth in some girls during infancy\n- Breathing irregularities when awake (breath-holding, fast breathing)\n\n**Always act promptly on**\n- Any regression — loss of hand use, babble or social skills at any age\n- Seizure-like episodes — these need prompt medical review, not a wait-and-see approach\n\n## When to seek help\n\"Wait and see\" is not the right approach when a child loses skills she once had. Regression — particularly of hand use combined with repetitive hand movements — warrants prompt review by a paediatrician, who can arrange the right medical and genetic assessment. Early support for communication, movement and daily skills can begin alongside that medical pathway, so your daughter keeps building on her strengths.\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 qualified clinician care — never from an online list or a single screen. Across 70+ centres in 4 states and 4.95 lakh+ families served, our teams build a warm, strengths-led plan around each child. Explore how we support communication through [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate), and learn more about the condition at [Rett syndrome](/).\n\n## Trusted sources\nAligned with WHO ICD-11 (LD90.0), and developmental guidance from the American Academy of Pediatrics, the CDC and NIMHANS. These describe the recognised pattern of early-normal development followed by regression, loss of purposeful hand use, and stereotypic hand movements in girls.\n\n**Next step —** if your daughter has lost skills she once had, message the Pinnacle clinical team on WhatsApp at +91 91001 81181 to arrange a developmental check.\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-girls","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-girls","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-rett-syndrome-in-girls-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Early Signs of Rett Syndrome in Girls","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Keep short phone videos of your daughter's hand use and play over a few weeks.
