I've been breastfeeding my lil Marz for two months we had been using the nipple shield for the better part of those two months. We had weaned off it completely right before his two month shots and after that we used it a little bit but then we were back on track and now he won't take my nipple with/ without it and I feel like I've failed. I just don't know what to do I really want to keep breastfeeding but I'm so stressed out about it
