DD2 is 9mo and BF. She has never taken to a dummy and finds it hard to self settle, so I usually BF her to sleep and co sleep. Recently she has started to bite/play with my nipples at the end of each feed. I have tried screaming fuck saying "no" very firmly but she is not getting it. My mum and sister say it's time for me to stop BF but I can't face the tears and really wanted to get to 12mo
Help!
