His fourth tooth came in this week. I can't remember which day. I am kicking myself for not writing it down. But it was early this week. Like maybe Tuesday. He is crawling perfectly now and is unstoppable. He is so fast that you can't take your eyes off him. He is even standing on his feet and using whatever he can to push across the floor so he can walk. I guess he needs a push toy now.
We got his high chair last night. It is going to work out pretty well, I think.
