Should I be worried my child might have developmental regression?

If your child seems to have lost a skill they once had — a word, a wave, a way of playing — that worry deserves attention, and there is a clear, hopeful next step.

In short

Developmental regression means losing skills a child once had — words, gestures, social warmth, play or motor abilities — rather than simply being slow to gain new ones. Unlike a delay, regression is a change worth checking promptly, because the kindest and most powerful response is early assessment. Worry is a reason to act calmly and soon — it is not, by itself, a diagnosis.

What is worth attention

Seek a check sooner rather than later if you notice:

• Losing words your child used to say, or going quiet after starting to speak
• Stopping eye contact, smiling or responding to their name when they used to
• Losing a gesture like waving, pointing or clapping
• A skill in play or self-care that has slipped backwards
• Loss of motor skills — sitting, crawling or walking they had managed before

A brief, isolated pause around illness or a big change can happen. A genuine, sustained loss of an established skill is the real flag — and it is one we want to look at without delay.

When to refer

Because regression can occasionally point to a medical cause as well as a developmental one, it should always be reviewed by a qualified clinician promptly — never watched and waited on for months. The sooner a child is assessed, the sooner the right support can begin, and outcomes are markedly better with early action.
