On Sunday evening Sam took his first two steps! He and Heath were playing and Heath stood him up. He can stand on his own pretty steadily now. Heath was enticing him to walk with a cookie and he took two tiny steps and then fell into Heath's lap.
I was actually very surprised when he took those steps because so far he's shown absolutely no interest in walking. Whenever I try to hold his hands and get him to walk he just squats down and starts crawling. The only timeline he's interested in is his own and walking is not on it right now. I think the steps were only a fluke. It'll probably be a few weeks or more before he starts walking in earnest. But, still it's worth documenting.
