With my first, I had to wear a nipple shield for the three months I breastfed her and for whatever reason my milk just stopped coming in completely. I was absolutely devastated! I just had my second girl two days ago, and she's already lost 9% of her weight. Her pedi is saying we'll have to supplement with formula if she has still lost weight by tomorrow. I'm feeding her every two hours, about 15 minutes on each side, if I can get her to stay awake. We haven't needed a nipple shield yet but to be honest my breasts are a bit sore, I'm guessing this is normal though? I really didn't want to hear I already need to supplement and I'm bummed out. 😥 not how I wanted to start this journey out.
