If you look close, you can barely see his two little nubbin' teeth on the bottom in the very front. Don't be fooled by the bubbles by his gum on the right of the picture! I took a bunch of pictures trying to catch those teeth, but just couldn't quite get it.
I realized this morning he has two teeth almost coming through up top. Funny thing is, it's not the middle two, it's the next two out from the center! That's going to look pretty funny if they really pop through first. :-)
