My baby has this habit of biting me while he nurses. Before, it was tolerable, but now, I may say deadly. It really hurts and no matter how I try to stop shrieking, I just can't. So he ends up looking at me, with an evilish grin. Sometimes, with a laugh even. How can I make him stop doing this? :(

As far as I know, it's best not to show a shocking emotion because this amuses a baby, for some reason I really don't know. Try your best to keep stern, although it may be a big challenge. You can also talk to your kid and make cues that it isn't a good thing to do. Eventually, he may learn from it.
