Poor baby :( my DD has been teething her molars for a couple months now :x
My chubbz(12mos) is cutting two, and you can see the points of 3 of his canines and his molars are starting to show up. I still only see canines up top though, no others(he just got his top fronts)
I feel your pain. Total crabbiness, barely sleeping. I feel terrible for him. Luckily now that he has 4 new ones he is starting to tolerate it a little better.
