They are young, 16 months old. I agree that it is normal, and it has been good for a while. I just hate that the other parents are getting mad. I may email the mom of the biters and see if I can back peddle a bit... I'll have to think about it. It has been going on for quite a while on and off. I just dont want to look wishy washy. lol Ugh... yay for bad days!
