YOUR QUESTION. A CLEARER NEXT STEP.
Early Signs of Rett Syndrome in Girls
Rett syndrome in girls often follows a pattern: apparently typical development for the first 6–18 months, then a slowing and loss of skills — especially loss of purposeful hand use, repetitive hand movements (wringing, washing, mouthing), reduced babble and eye contact, and unsteady walking. Any regression warrants prompt paediatric review; only a clinician can assess and confirm.

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.
In short
Rett 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.
Early signs to notice
The early pattern
- A stretch of apparently typical development in the first 6–18 months
- A slowing down, then a loss, of skills the child had already gained
Hand changes (a hallmark)
- Loss of purposeful hand use — no longer reaching, grasping or holding as before
- Repetitive hand movements: wringing, washing, clapping, tapping or hand-to-mouth
Communication and social changes
- Reduced babble, eye contact or social engagement, sometimes after it had been present
- Eye gaze may later become a strong way she communicates
Movement and growth
- Unsteady or wide-based walking, or difficulty walking
- Slowing of head growth in some girls during infancy
- Breathing irregularities when awake (breath-holding, fast breathing)
Always act promptly on
- Any regression — loss of hand use, babble or social skills at any age
- Seizure-like episodes — these need prompt medical review, not a wait-and-see approach
When to seek help
"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.
The Pinnacle way
A clinical AbilityScore® 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, and learn more about the condition at Rett syndrome.
Trusted sources
Aligned 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.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Escalate to a same-week paediatric review on any regression — loss of purposeful hand use, babble or social engagement — especially with repetitive hand movements (wringing, washing, mouthing), slowing head growth, or any seizure-like episode, which needs prompt medical care.
In everyday life
Keep short phone videos of your daughter's hand use and play over a few weeks. A clear before-and-after of how she reaches, holds and engages is one of the most useful things you can show a clinician.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
At what age do signs of Rett syndrome usually appear?
Most girls develop apparently typically for the first 6–18 months, then show a slowing and loss of skills. The change is often first noticed in this window, particularly around hand use and babble.
What is the most recognisable early sign?
Loss of purposeful hand use — no longer reaching, grasping or holding as before — alongside repetitive hand movements such as wringing, washing, clapping or hand-to-mouth. This combination is a well-recognised hallmark.
My daughter is losing skills she once had. What should I do?
Any regression deserves a prompt paediatric review rather than waiting. Note when changes began, keep short videos if you can, and seek a developmental check. A doctor can arrange the right medical and genetic assessment.
Does Rett syndrome affect only girls?
It is recognised predominantly in girls. The pattern and severity vary widely between children, which is why an individual clinical assessment matters more than any list.
