Where to start for a child with developmental regression

When a child loses skills they once had — words, play, movement or social warmth — knowing exactly where to begin can turn worry into a clear, calm plan.

In short

Start with a prompt medical and developmental review, because developmental regression — losing skills a child had already gained — always deserves timely professional attention rather than waiting. Begin by speaking to your paediatrician and arranging a developmental assessment, so a clinician can understand what is happening and rule out any cause that needs medical care first. From there, a tailored therapy plan can be built around your child's strengths. Acting early gives your child the best possible support.

Where to begin, step by step

1. See your paediatrician promptly. Regression — especially loss of words, social connection, motor skills or self-care abilities — should be reviewed without delay. Your doctor can check for any underlying medical cause and guide next steps.
2. Note what changed and when. Jot down which skills your child has lost, roughly when you noticed, and whether the change was sudden or gradual. Short phone videos of before-and-now help the clinician enormously.
3. Arrange a developmental assessment. A structured, clinician-led evaluation maps your child's current abilities across communication, movement, play, thinking and daily living — and identifies where support will help most.
4. Begin a tailored therapy plan. Depending on findings, this may include speech therapy, occupational therapy, physiotherapy or behavioural support — always shaped around your individual child, with you coached as a partner.

Regression is a signal to act rather than to panic — and the earlier you begin, the more the team can do.

When to seek a check

Seek a review as soon as you notice a child losing skills they previously had — talking, walking, using their hands, responding to their name, or playing as before. This is not a watch-and-wait situation; a clinician should see your child promptly to understand the cause and start the right support.
