anyone struggle with thier little one having tummy troubles as newborns? my little girl is 5 weeks old and ever since I put her on formula she has been having the worst problems. (breastfeeding wasn't working for me I gave it my all) My daughter was allergic to the regular enfamil it caused her to bleed so she got switched to prosobee which made her really constipated so her doc switched her again to nutramigen. she's been doing great on the nutramigen..it's been 2 or 3 weeks on it but Saturday I started seeing blood in her stool again. I called her doc he hasn't called back. had anyone experienced this? I'm trying to breast feed again this is just rediculois I feel so bad for her 😢
