After a long drought, Anthony seems to be getting some more teeth to add to the 8 he already has. We're seeing a lot of the above and he's been waking up during the night, which is unusual for him.

Anthony's got 4 central incisors and 4 first molars. I think I felt one today on the bottom front, what this chart calls the lateral incisor. There might be more, but you put your finger in there at your own peril!
