Hey I have my baby march 3,2012 but I'm having a c-section so he going to take it the 25 of feb. I went to the emergency room about 2 weeks ago and they said I'm not dehydrated but I'm having all the symptoms of the dehydration stage... what do I suppose to do?

Do you mean you are going to have a C-section February 25, 2013? Not that you had your baby March 3, 2012?
You need to stop using the ER, and see your OB/GYN at regular appointments. We don't even know why you are having a C-section.
