First, I love the park pics. What a beautiful backdrop! I wish we had something like that nearby. Well, then again, since its only 30 degrees here, picture taking would be slightly limited outside with the kid. I really need to move to a place with a summer-like Christmas season!
Second, I was equally delighted with the first pull to stand (which happened the same day as crawling so we had a lot of excitement). Now that he can pull himself up, though, he's everywhere and a total destroyer. Great example: I went to check on him last night in the monitor. The picture I get is the floor and it's on it's side and, in the background, I hear heavy breathing. I go in his room, the camera is on the floor and he's holding on to the crib bars jumping up and down. At that point, he started crying since he'd been caught. That pull to stand turns them into sneaky little devils!
