Good evening ladies. We've been on IV for our daughter for 3.5 months now. She started having diarrhea. As usual, once a day but very watery. There's no fever, she doesn't complain about her tummy, she's active. Everything is still like before but watery stool. I can't even get an analysis done, everything soaks up in diapers. I made an appointment with the doctor. I wanted to hear your advice, maybe someone had this experience?
