My LO's biting has gotten out of control. He not only bites when he nurses, but he also just randomly bites arms, the tops of my boobs, noses, etc. It is both painful and annoying!

He is teething like crazy (5th tooth is coming in now) so I know it is probably because his teeth hurt, but is there any way to stop this behavior at this point? Is he even old enough to understand, "No, don't bite?" Sometimes when he bites really hard we yelp in pain and he cries, but it doesn't seem to deter the behavior.

He is biting multiple times a day at this point. Is this fixable or just something we need to ride out until teething is over? He has no interest in Sophie, teething rings, etc. He just wants to teeth on mommy and daddy.
