What to expect as your child with Rett syndrome grows up

Rett syndrome unfolds in stages, and at every one of them your daughter remains your daughter — known, loved, and able to grow with the right support around her.

In short

Rett syndrome typically follows a recognised pattern over the years — a period of regression, then a long, often more settled phase, with communication, movement and daily living needs evolving as your child grows. Many girls with Rett go on to live into adulthood, and with consistent, team-based support they continue to build connection, comfort and skills throughout life. What lies ahead is best planned gently, one stage at a time, alongside a clinical and therapy team who know your child.

What growing up often looks like

Rett syndrome usually moves through broadly understood stages, though every child's journey is her own:

• After early regression — many children pass through an early period where some skills (hand use, babble) fade. This is often the hardest phase for families, and it does not mean progress stops forever.
• A more stable plateau — for many girls, after the early years comes a longer, calmer phase where eye contact, alertness and connection often improve, even as motor challenges remain. Purposeful eye gaze frequently becomes a powerful route to communication.
• Communication never stops mattering — even when speech is limited, eye-gaze devices, switches and partner-supported strategies let your child make choices, share preferences and stay in relationship with you.
• Movement and the body — hand stereotypies, walking ability, scoliosis, muscle tone, breathing patterns and bone health are watched over time, supported by physiotherapy, occupational therapy and regular paediatric and orthopaedic review.
• Health to monitor lifelong — seizures, feeding and swallowing, gut comfort, sleep and heart rhythm (QT) need ongoing medical oversight; therapy works alongside, never instead of, this care.
• Into adulthood — with good support many women with Rett live well into adulthood. Planning ahead for adult care, equipment, mobility and meaningful daily activity helps each stage feel prepared for, not feared.

The steady aim across the years is comfort, communication and participation — helping your child stay connected and as independent as possible at every age.

When to seek a check

Seek prompt medical review for new or worsening seizures, breath-holding or breathing changes, signs of swallowing difficulty (coughing or wet voice during feeds), a curving spine, or any episode of collapse or unusual heart symptoms. Regular paediatric and specialist follow-up is essential throughout childhood and into adult care.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or online form. From there your child receives a whole-picture profile and a plan that grows with her, through coordinated communication, movement and daily-living support — explore our network and approach and how the AbilityScore® assessment maps your child's strengths. For communication through eye-gaze and partner strategies, our speech and language therapy is built around children who communicate without words.
