sounds like teething to me too.

for safety, i would offer a whole apple to bite down on, not apple pieces. I 2nd allycat's wet facewasher idea too.

even when you can't see teeth yet, the teeth apparently go up and down inside the gum, ready to make space for the tooth to eventually pop up. my bub had this happen for MONTHS before actual tooth showed up.

Have you heard of the amber teething necklaces you put on bubs?
