Infant Dehydrating

Hi everyone, I'm not sure where to put this question, but have a lot of respect for those of you who frequent this forum so am trying here. I have a friend with a 1 yr old baby who is in the hospital suffering from severe dehydration. The Drs. have no clue why or what she has, and are basically just keeping her there where she'll probubly die, her condition isn't improving at all. Does anyone have ANY suggestions? Would this be her Kidney's? What could be causing this? It seems there is so much out there right now, I'm just praying that things turn around soon. Thank You so much! Tweet
