I did wonder if he slept so bad because he was getting hot, so I starting dressing him in a onesie at night with his sleep sack over it. Not sure if that makes a difference, but he doesn't feel as hot when I pick him up. Going to bed around 10 has been really nice too. I feed him sometime between 9-9:30, and then we head up when he's done. It was interesting that this week and last week he slept bad Sunday and Monday nights. We'll see if it happens again this week (please no!).
He's really getting more interactive. He loves to look in the mirror at his little face, and he's starting to mimic my face. If I smile at him, then he will smile back (if he's not upset). I can tell that his eyesight is developing more and more every day as he loves to look around at the world. That's why he loves being held facing out or over your shoulder. It's fun to watch him grow!
