HOW TO HELP YOUR BABY TO CRAWL
From the start, give your baby tummy time long before your baby’s ready to crawl. Placing your baby on his tummy and playing with him while he’s awake and alert for several minutes a few times a day will help to develop muscles that he needs to crawl.
Incentives to move.
The best and easiest way to encourage crawling is to place his toys and other favorite objects ( like yourself ) just beyond his reach, these are incentives for your baby to try, crawl and reach for them.
A crawling baby can get into a lot of mischief. Make sure your house is childproofed, do ensure a special emphasis on stairway gates. Your baby will be drawn to stairs, which can be dangerous, so keep them off-limits until he’s really mastered walking (usually by about 18 months). Even then, it’s important to supervise him closely.
