"Better upper body strength and head control allow your baby to prop himself up on his elbows when he is lying on his stomach. Over the next month or so, he'll become strong enough to push up on fully extended arms. He can open his hands halfway and shut them at will. Your face remains his favorite thing to look at. Your baby laughs out loud and enjoys imitating your giggles and facial expressions. Your child distinguishes several hundred spoken sounds now. And by putting objects in his mouth-everything from your hair to his fist to a favorite toy- he is learning a lot about size, shape, temperature and texture."

Keegan is now sleeping in his own room every night. Once I moved up to a faster flow nippple on his bottle he seems less hungry overnight. So now he goes down between 9 and 10 pm and wakes at 2 am. Then he'll sleep again until 7am. Sometimes I can get him back to sleep and other times he is raring to go. But it is so much better than before. Also he seems to be able to put himself to sleep by sucking on his hand. I have also put him in a walker stuffed with a towel to keep him from flopping over. He likes to be in it and watch me work in the kitchen. Sometimes he accidentally moves his feet and pushes it backwards. It was a hand me down from a friend so I haven't decided if I want to get him a more complicated version like an exersaucer. The toys he does play with seem plenty for now.
Keegan has started drooling a lot and putting his hand in his mouth even when he isn't hungry. I wonder if he is getting close to teething. I have no idea how to tell since he doesn't seem to be in pain at all. Maybe lots of drooling is normal at this point. I'll have to ask at my mother's group.
Keegan is also more verbal. Prone to shrieking for no apparent reason or making cooing noises like he is trying to tell us something. He is currently working on the "b" sound. And he loves it when you make the "p" or "b" sounds. Like saying "Poppa's porkchop puppy" cracks him up. Or repeating "bonkers baby" over and over is a favorite too.
His two month checkup appointment isn't for another couple of weeks so we'll have to wait until then to find out his measurements. I didn't think that much about it until several people told me he was big, but I think they just don't know what a 4 month old boy is supposed to look like.
