From Baby Center: Most babies get new teeth in this order: First the bottom two middle ones, then the top two middle ones, then the ones along the sides and back.
I tried for quite a while to get a picture of babe's tooth. He officially has one upper chomper - smooth sailing on the bottom gums though. Yes, he is not the norm by getting a first tooth on the top, but I would hate for him to be run of the mill. He enjoys running his tongue over it and sort of making sucking noises. It amuses me greatly! I love this guy more and more each day which is good for those days where he moans for an hour or so in the evening. Must go as he is headed towards mischief as usual!
