Sitting up

Thaddeus is doing great sitting up! Today in church I took him into the nursery and sat him down on the floor and he just sat there. He didn't need any help at all. And he sat there for a long time, not just a minute. I kept waiting for him to fall over but he didn't. It seems like this has come out of nowhere. Just a week ago he couldn't sit up on his own for more than a few seconds, and he would just flop over. Yesterday he sat up for a short period of time. I guess he figured out he can do it and he's going for it. I'm so proud!
