I wasnt sure where to post this so Ill try here.. My 18 month old daughter has to see an endochrinologist because my Dr thinks she has this disorder. I googled it and have a basic understanding of what it is. Is there anyone who has a child with this or has it themselves who can give me more of the personal experience? Its not diabetes. It sounds like the kidneys dont hang on to much water for the body to use, so she drinks alot and pees like crazy, and yet can become dehydrated easier than other people. I change her every hour to avoid soaking her pants/blankets/carseat. That was what prompted the urinalysis and blood work. Dr was looking for diabetes.
