I also want to know how old he is. If he isn't that old and he's biting it'll probably pass especially if he hasn't gotten all his teeth yet or whatever. Lilly bites us on our hands and toes and has drew blood on our hands before but just little nicks where we tried pulling away. She's only 3 months though and hasn't gotten all her teeth and many people have told us she'd stop. Plus, I plan on taking her to classes where they can hopefully make her quit but I really just think it's because of her age. I just don't see how this can't be put under control or to a stop instead of getting rid of her and even so to a pound or something..
I, personally, could never imagine doing such a thing.
