My DS is the same. The first two teeth were a nightmare. The next two were equally hellish, and all others after that have been fine. I noticed today that he has cut another tooth. THe only thing is that he has had runny nappies and a sore bottom, but no sleep disturbances.

He may also be having a growth spurt - hence being hungry, and waking up wanting a feed.

Good luck, and give it a couple of weeks and it might pass.
