My 15 weeks old baby girl has been trying to commando crawl recently and I am getting really worried. Any tips/ advices to ensure that she is not over exerting or hurting herself in the process?

It is normal for babies to start off with cammando crawl. My baby is also one of them. Crawling baby can get into a lot of mischief. Do make sure your house is child-proofed, and put stair gates at the top and bottom of the stairs and gate at the kitchen. As soon as your baby can crawl, or pull herself up to standing, take cot toys and bumpers out of her cot. Your baby may climb on to them and fall out of her cot. You might want to adjust the cot lower. You can also consider getting a play yard for her. I got mine from Q10: http://www.qoo10.sg/gmkt.inc/Mobile/Goods/Goods.aspx?goodscode=423945877&stcode=77

thanks emeris! your baby started off at 15 weeks too?
