If your little one is pulling himself onto all fours and rocking back and forth, then the chances are it won’t be long before he’s mobile. This typically happens anywhere between seven and 10 months, with most babies supporting their body weight on their hands and knees, and propelling themselves forward by moving alternate arms and legs.
That said, all babies are different and some devise their own techniques for getting around, whether it’s shuffling along on their bottoms, inching along on their stomachs, rolling, doing combat crawls, or even half walking/half crawling. No matter how your baby chooses to get around, these methods are all considered perfectly normal. Apart from anything, moving shows a motivation to get somewhere (anywhere!), and any type of crawling will help him develop the muscles that will eventually enable him to walk.
And don’t fret if your baby shows no interest in crawling even after 10 months. Some babies never bother to crawl at all before walking, which is rare but doesn’t usually signal a physical or mental delay. If you’re concerned, speak to your health visitor or GP.
