Any Moms been dehydrated while breastfeeding? My Daughter is 5 weeks old tomorrow and I had problems while I was pregnant but I'm feeling dehydrated again and tonight it's really bad. I've been chugging water but my Daughter has been wanting to every 2 to 3 hours lately so as soon as I start to feel better I feel worse again. What can I do?!
