Why is my child late to crawl or walk?

When the other babies at the playgroup are crawling and yours isn't quite there yet, it's natural to wonder — and asking is exactly the right thing to do.

In short

Most children crawl between 6 and 10 months and walk between 9 and 18 months — and that's a wide, healthy range. A child can be a little later than a cousin or neighbour and still be developing perfectly well; some babies even skip crawling and go straight to pulling up and walking. Late motor milestones can have gentle explanations like muscle tone, temperament, more time spent carried, or simply individual pace — but they are also worth a quick check so you have clarity and peace of mind.

Common reasons a child may be later

• Their own pace — within the typical range, babies reach milestones in their own order and time.
• Body readiness — strength, balance and muscle tone all build gradually; floor time and tummy time help.
• Style of moving — some babies bottom-shuffle, roll or commando-crawl instead, then walk well.
• Less practice opportunity — lots of time in walkers, bouncers or being carried means less time to push, pull and explore on the floor.
• A previous illness or being born early — premature babies are often measured from their corrected age, so they catch up on their own timeline.

When it's worth a closer look

Do arrange a developmental check if your child: is not sitting without support by around 9 months, not bearing weight on their legs or pulling to stand by around 12 months, not walking by 18 months, uses one side of the body much more than the other, feels very stiff or very floppy, or has lost a movement skill they once had. These don't mean something is wrong — they simply mean a clinician should take a look, the earlier the better.

The Pinnacle way

Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online form. If you'd like reassurance, our team can gently assess why your child may be late to crawl or walk, build a simple movement and physiotherapy plan if needed, and explain how the AbilityScore gives you a clear starting point.
