Once your baby can sit up on his own without toppling over (usually after 6 months), he'll start trying to get even more mobile by moving about. Over the next two months, your baby may start a number of "pre-crawling" moves like creeping (pushing himself around on his belly); scooting (crawling on one leg and dragging the other); or a combination of rolling, rocking, and squirming on his stomach, bottom, or back. To encourage your baby to move, give him plenty of space and let him loose to explore. Placing favorite toys nearby and just out of reach may tempt your baby to lurch forward while he's sitting up or during tummy time. Don't be alarmed if your baby initially starts creeping backwards. This is very common since it's much easier for him to move those heavy legs backward than drag them along forward. He'll get going in the right direction soon enough. Eventually, this early locomotion may progress to true hands-and-knees crawling, but don't worry if your baby doesn't ever take off on all fours. It's common for some babies to skip crawling all together and go directly to standing and walking. Because crawling is not considered an essential stage of development, a "late" crawler or an infant who never crawls is no cause for concern.
