For the past day and a half my baby has spit up (I think, maybe vomit?) very large amounts. This has happened 3-4 times and it's a ton! Enough to soak her clothes and I've been keeping a spare blanket by her just in case to try and catch it all. She is about 10 days old and I have been breastfeeding. I've tried different positions, keeping her upright and burping often but it keeps happening and I don't know what to do! I'm feeling very discouraged and I'm afraid to leave the house or anything because I feel like she's going to explode any minute. Has this happened to anyone? Any advice would be greatly appreciated.
