You can't steal him! He's mine, all mine!
I've seen lots of pics of babies in bumbos and it seems like a lot of the younger ones are kind of slumped in it, he does really well. In the pics above where he has the crazy hair i'm obviously supporting him but I can take my hand away when he's like that and he'll sit for a bit (not long, only like 5 seconds) before starting to tip over. He has awesome head control too, it doesn't really flop much at all, only when he's tired.
Next week he goes to the doctor. I can't wait to see how much he's grown. He has to have his shots too, i'm nervous about that.
