Molars for Iain

So a few days ago Julie was playing with Iain (she had him upside down) and had a clear view into his mouth and she saw that one of his molars was in (on the top right side) and that the other 3 were starting to come in. My poor poor baby. I mean I brush his teeth every day and I guess I just never realized that he was getting them (I use a finger brush and I get the job done and get my finger out of there before he bits me).
