Not that I have any kids of my own..... and I've only seen what a good friend of mine did for her 10m.o. She doesnt smack, but dont know if she follows "gentle parenting" or not. When ever her bub bit, she would quickly, sternly and with a slightly louder voice, say "NO" then pick him up and put him away from her, on the floor on a playmat etc, just away from her. He didnt like that much and made the association in about a week. I dont think there has been a problem since..... thank god! I was only on the receiving end once, and that was enough!

Dont know if this method might backfire later....... wonder whether hes going to be one of those kids that always say "no" to everything...... cant wait to see her solution to that
