My son is five months old, he has had his two bottom teeth for over a month and never bit me until the past few days. Since this weekend he has bit down on me several times. I reponded with Ouch! When he is drowsy or going to sleep, he cries when I say ouch. He also does this when he is wide awake and when I say ouch he laughs at me. I think he enjoys the response. So, I have tried to just pay attenion to him really closely and when he looks like he going to stop nursing, I pull him away. If he does it a couple of times I have stopped nursing him and just let him wait until he is hungrier. If he is really hungry then he doesn't waste time nibbling on me. If anyone has any better suggestions I would really appreciate it. It really hurts when he bites and I don't know if I'll be able to make it when those top ones come in. I really want to make it until he is at least 1 year old.
