As his movement develops, so does his curiosity about the world around him and his ability to investigate places he wasn't able to go before. Once again, you'll have to look around your home from a different eye level. Childproof your home as much as possible, so your new walker can experience the freedom and excitement of exploration. Different babies walk at different times. Some proficient crawlers will walk later, since they already have the ability to get around quite well.
Some younger siblings walk early, just to keep up with the older kids.
If your baby hasn't started walking by the time he's one year old, he probably will within the next few months. They keep their legs wide apart and seem to hesitate between each step, jerking side to side as they move one foot forward, then the next. They generally get upright by putting their hands out in front, lifting their bottoms, and pulling their feet under them. Not very graceful, but it works. Your toddler will experience his share of falls, but if you don't overreact to these tumbles, he should get right back up and try again.
