About 3 days ago my baby "bit" the end of my nipple (first time)
the previouse couple of days she nipped a few times during the day
today she has done it at least twice at every feed 
at the last feed she must have done it 3 - 4 times on each side
I try not to react but it HURTS, and i cant help flinching / going ouch etc etc
Is this just a phase? Will it stop soon? (please say it will)
She does it when she hasnt even nearly finished and still wants more milk, and I dont feel like i can not let her have any-more milk once she has bitten me
