My 7 month old son has just recently begun biting my nipple during a feed. He has done it about 5 times, each time I have taken him off and said "ouch", but yesterday, he drew blood! When i first started breastfeeding, I suffered badly with Mastitis, (as I did with my daughter too)heavily cracked and bleeding nipples and thrush in each breast. I persevered through all that, so will not give up without a fight!! Any advice or tips, gratefully received.
