DS is 6 months and got his first 2 teeth two weeks ago. He bit me once, minorly, soon after he got them but no other issues. Tonight he has bitten me 4 times, twice minorly and twice very painfully, enough to make me check if he'd drawn blood. Each minor time I've removed him and firmly said 'no', but both other times I've involuntarily yelped and sharply removed him. The first time I did that tonight he froze, then burst into tears as he knew I was cross, the second time he didn't seem bothered. I felt horrid for making him cry but know he has to learn not to do this.
I've fed him again since, but felt anxious the whole time, and as each stronger bite was on a different side I'm tender on both sides. Does anyone have any advice or experience to share as I really don't want to stop BF yet, and he doesn't take a bottle anyway, but don't want to carry on feeling anxious about feeding 
Thank you
