Casey's tummy time video

I know a lot of you like to see videos of Casey so here are a couple new ones. I recorded the first part of tummy-time and he looked pretty content, but you can rest assured that he melted down about a minute later (doesn't really like tummy-time very well). He is much happier laying on his back kicking the little ball on his play mat, although he's not terribly energetic in this video. He's really getting big and is on the verge of being able to hold up his head. He can sit up (propped) for a few minutes for pictures but eventually starts to lean one way or the other.
