Our Little Bum Scooter

Jack used to use his arms, throw them out in front of him and then scoot him bum toward his hands. We figured this would eventually lead to crawling. He then realized that if he didn't use his hands at all he could really get momentum with arms in the air and his body. He gets ALL over the house this way. I think the smoothness of wood floors helps. Here's a demonstration at Gramma's house.
