On the move

My baby is crawling! It is kind of bittersweet. Before he could crawl he would get on all fours and lift himself up on his toes. He even figured our how to go from his knees to a sit position, yet could not crawl. Finally, at my moms house, he took his first few arm-leg-arm movements. He was rather clumsy, but has gotten so much faster in just 3 days. I think that he does all his milestones at my mom's house. While we were at her house he first smiled, first laughed, first went to a sit position, and now first crawled. Crazy!! Wow, he is growing up so fast.
