Don't give up breastfeeding just yet! I breastfed my daughter for 14 months. She, too, had a thing for biting me when she was around six months old. I know it's painful, but with patience (and maybe some Jack Daniels--just kidding) you can work through this. Whenever my daughter bit me, I'd immediately take her off my breast and (with eye contact made) tell her 'no'. Then try to nurse again. This works! Oh, and make sure your son has plenty of 'chew' toys for his new teeth. This is a necessity. Good luck!
