Isaac has teeth :)

The second tooth arrived this week so Isaac officially has "teeth." It seems like he's still working on more already. I guess if we can get it over with all at once, that would be fine.

David taught Isaac a new trick - pulling himself up in the crib. Fortunately, he has to start sitting up to do it and he still hasn't figured out how to go to sitting from lying down. I guess we should start thinking about lowering the mattress, just in case...
