How your baby start to crawl?
Crawling is your baby’s first way of getting around efficiently on his own. In the traditional crawl, he’ll start by learning to balance on his hands and knees. Then he’ll figure out how to move forward and backward by pushing off with his knees. At the same time, he’ll be strengthening the muscles that will soon enable him to walk.
When it develops
Most babies learn to crawl between the ages between 7 to 10 months. Your baby may opt for another method of locomotion around this time, though – like bottom shuffling (scooting around on her bottom, using a hand behind and a foot in front to propel herself), slithering on her stomach, or rolling across the room.
Don’t worry about her style, no matter how your baby does it. Some babies don’t crawl and move directly to pulling up, standing, cruising (furniture walking) and walking.
Signs that your baby’s ready to crawl, and the different forms it can take.
How it develops
Your baby will likely start crawling soon after he’s able to sit well without support (probably by the time he’s 8 months old). After this point, he can hold his head up to look around, and his arm, leg, and back muscles are strong enough to keep him from falling on the floor when he gets up on his hands and knees.
Over a couple of months, your baby will gradually learn to move confidently from a sitting position to being on all fours, and he’ll soon realize he can rock back and forth when his limbs are straight and his trunk is parallel to the floor.
Somewhere around 9 or 10 months, he’ll figure out that pushing off with his knees gives him just the boost he needs to go mobile. As he gains proficiency, he’ll learn to go from a crawling position back into a sitting position.
He’ll also master the advanced technique that pediatrician William Sears calls “cross-crawling” – moving one arm and the opposite leg together when he moves forward, rather than using an arm and a leg from the same side. After that, practice makes perfect. Look for him to be a really competent crawler by the time he’s a year old.
