Has your son stopped biting?
Is there any hope for mine? lol It's my son-22mo, as well that is the biter. He only bites on other child-1yo and seems to be when that child plays with/touches something my son doesn't want him to play with/touch. And its not even something he was playing with himself at the time. I feel horrible because I've only had this other boy for 6 weeks and I really like him and his mom. I don't want her to get pissed off and take him else where.

We also have tried everything to get him to stop. I am doing the shadowing, but he still managed to get a bite in today. Not sure what else to do.
