Carrie - you are doing the best job - loving and caring for your child!
My son bit - - a lot! It was so hard for me to stop it, to "fix" it - it was when he was in preschool, I worked in the infant room, he was in the toddler room - we got sent home because he bit someone - I took him and I was in tears, I was so mad that I couldnt stop this behavior -
the one thing that stopped his biting? Hearing aids... believe it or not, once he was diagnosed and had aids, and was put in the total communication school, the biting disappeared - (I'm sure it was a combination of things, from outgrowing, to being able to communicate other than with his mouth/ ie biting)
but for your child, I just wanted you to know, I understand how hard it is to deal with something you really cant control.

Hope you do have a magical time - and I do hope you come back and report on the thread how things went!!
