Girls, hello, my daughter is one year and five months old and before bed I give her breast milk so she can fall asleep, but when she sucks on one and takes her nails to scratch me in the other nipple, sometimes it's pinching, it's really unpleasant and annoying. I'm already about to lose it, what should I do? Can you help me stop breastfeeding? Maybe?
