Yesterday Henry's first tooth broke through. It is just tiny little ridges on his bottom center left gum. When it's a little bigger I'll try to get a picture.
Also Henry has some new exercises. He gets his belly off the ground, gets on his hands and knees and rocks. He also sometime balances just on his hands and feet, sticking his butt in the air. It's great. He will be crawling soon. Although he's already pretty good at rolling and scooting backwards and somehow getting to a whole different side of the room. What a show off!
