How do I get my 9 month old to stop biting. I don't know if he does it because of teething or what but he loves biting skin, especially our faces. He does it so vigorously and gets mad when you won't let him. I try to close his mouth and tell him "no bite" but idk if it's working. I would ask my family and friends on Facebook but I know they would just tell me to start spanking him. We haven't decided if we're going to spank yet or not but we're leaning towards no and even if we did, I think this is too young an age to start. Any suggestions?
