Ouch! My DS2 was a biter, he was so quick I could never beat him to it. He bit really hard too I swear he was going to chomp my nipple off, he would make me bleed! Just over two months of that and my nipples had enough, 12 months old and he weaned. I used to just take him off and put him down wait 5-10 mins and then go again.

I hope she stops real soon!
