Early Signs of Rett Syndrome in a 2-Year-Old Girl

Every little girl grows at her own pace — but when early skills seem to slow or slip away, a gentle, timely look can make all the difference.

In short

Rett Syndrome is a rare neurodevelopmental condition seen mostly in girls, where development typically appears normal for the first 6–18 months and is then followed by a slowing or loss of skills. In a 2-year-old, the most telling early signs are a loss of purposeful hand use with new repetitive hand movements (wringing, washing, mouthing or clapping), slowing head growth, loss of spoken words or social engagement, and emerging difficulties with walking or coordination. These signs deserve a prompt developmental check — they are a pattern to recognise, never something for you to diagnose at home.

Early signs to watch in a 2-year-old

The most characteristic clue — the hands

• Loss of purposeful hand skills she once had (holding a spoon, picking up small toys)
• New, repetitive hand movements — wringing, washing-like rubbing, squeezing, clapping or bringing hands to the mouth

Communication and social signs

• Loss of babble or words she had begun to use
• Reduced eye contact or social interest that had previously been present

Movement and growth

• Slowing of head growth (your paediatrician may notice this on the growth chart)
• Unsteady, wide-based or stiff walking, or not walking yet
• Episodes of breath-holding, fast breathing or teeth-grinding while awake

The key pattern

• A period of typical development followed by a plateau and then loss of skills — regression — is the single most important reason to seek a check promptly.

When to seek help

Any loss of previously acquired skills — hand use, words, babble or social connection — at any age is a reason to act, not to wait and watch. Speak to your paediatrician promptly; they may arrange a developmental review and, where the pattern fits, refer for genetic testing, as Rett Syndrome is linked to a specific gene change and can be confirmed clinically. Early support for movement, communication and daily skills helps your daughter thrive while assessment is arranged.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from a web page or a checklist at home. Our therapists build a warm, multi-domain picture of how your daughter moves, communicates and connects, and create a plan that grows with her. Explore occupational therapy for hand use and daily skills, and speech therapy for communication. Learn more about how we support families on our home page.

Trusted sources

Aligned with WHO ICD-11 (LD90.0), and developmental guidance from the American Academy of Pediatrics and CDC's "Learn the Signs. Act Early." programme. These describe the typical pattern of early-normal development followed by regression and loss of purposeful hand use that characterises Rett Syndrome.
