My child stopped talking and lost words — should I worry?

When a child loses words they once used happily, a parent's worry is real — and it is exactly the right instinct to act on, gently and promptly.

In short

Yes, this is worth acting on — not with panic, but with a prompt developmental check. A genuine loss of words or skills a child already had (called developmental regression) is one of the few signs we always recommend reviewing without waiting, because early attention gives your child the best possible support. Many children who regress go on to do well with the right help; the important thing is to have it looked at sooner rather than later.

What this can mean — and why a check matters

Losing previously-acquired words can have several explanations, and only a qualified clinician can tell which applies to your child:

• Hearing changes — even temporary hearing loss from glue ear or repeated ear infections can quietly erode speech. This is common and very treatable, so hearing is usually checked first.
• A pause around a big change — illness, a new sibling, a house move or starting daycare can briefly affect talking. This usually recovers, but a true loss of skills is different from a quiet phase.
• A developmental difference — for some children, regression in words (often alongside changes in eye contact, gestures, play or social connection) is an early sign of an autism spectrum or other developmental profile, where early support makes a real difference.
• Rarely, a medical cause — a sudden or marked loss of several skills should be seen promptly by a doctor to rule out anything needing medical attention.

Because the right path depends entirely on the cause, the kindest, most empowering step is a structured check rather than waiting and watching alone.

When to act

Arrange a check now — without waiting for the next milestone visit — if your child has lost words they used to say, stopped responding to their name, dropped gestures like waving or pointing, or pulled back from play and connection they previously enjoyed. A sudden, dramatic loss of multiple skills warrants a same-week doctor's review.
