To me, they look a little sunk in, but I might just be worrying.
It's really obvious when he's stretching out a little. Like he's leaning up to smell something or trying to climb up. It seems like it makes sense for him to look thinner, but he definitely gets the ) ( shape. It's always harder to tell when he's crouching up next to my shirt or something. I'll try to get a pic or two.
Should he be fully grown already? I thought he was still a baby!
