You can't feel it yet and it looks teeny tiny but Sara has another tooth revealing itself on the top. They usually come in pairs but it is so small and so slow to come in that it's hard to tell if there is a partner. That gives her 3, possibly 4.
Adam must be working on more teeth, as well. He is drooling like crazy. The other day after nap time he was standing in his crib. When I got in there, the whole front of his shirt was wet, there was spit running down the crib, and a wet spot on the carpet!
