Or Tiny, as I call him. He's just over 3 months old now. And he's stretching out of his 6-9 month clothes. Seriously. He's just that fat. DearWife will argue with me on that "babies can't be fat" - but she's wrong. If you put him on his back, he looks eerily similar to a komodo dragon.
It's a good thing too. We moved him into the nursery, and he's been very cool with it. On Wednesday, DearWife went to BodyPump. I (somewhat miraculously) got the big boys to bed early. Tiny screamed through the book reading portion of our routine, and wasn't too happy when I tried to sing to his brothers.
But then I turned on baseball. And he calmed down. And went to sleep. And stayed asleep...for 10 more hours! Amazing little kid. I attribute it all to his eating.
