Good evening girls Please tell me when you stop breastfeeding, do you need to breastfeed? I had mastitis when my son was 2 months old, now it's been two months since then, and one side of my breast is hard like a cork, it feels like it has turned over on its side. It's hard. They say just bear with it, but I'm afraid.
