So my milk didnt in until a few days after birth so my baby girl learned to suck on a bottle nipple. She use to latch on my nipple but now she wont unless theres a nipple shield. ive been trying to get her to relatch to just my nipple but she won't. Any ideas? Also my other nipple is inverted. ive tried making it cold, sticking it out my self, and using a nipple shield but it is really painful throughout the whole feeding. so I have stuck to pumping that boob.
