Crawling Backwards

My baby is sitting up on his own and also trying to crawl. Although he hasn't mastered this yet, it's cute to see him getting on all fours and crawling backwards, not forward yet. He runs into the sofa and other furniture pieces. When he wants to go somewhere, he simply rolls and goes backwards. Can't wait to see if he's going to be a crawler. Some babies just don't master the skill of crawling. So, I'll just have to wait and see.
