Most babies start to crawl sometime between seven and ten months. That’s most, but certainly not all.
It’s hard to put an exact time on it, firstly because all our little ones are different and secondly because… well, what even counts as crawling? Lots of babies opt for the bottom shuffle (a classy move if ever we’ve seen one ), whereas others use their elbows like they’re in an army assault course. Some even skip the crawling stage altogether!
Usually, you don’t need to be concerned about the rate your baby is learning to crawl as long as your baby seems to be progressing. But if you're worried that your baby isn't showing any signs of moving by 12 months, ask your health visitor or doctor for advice.
