Hi!
It's not anybody's fault. It's just we don't understand physiology. I just went thru all of those biology classes in college and started the nursing program this semester, but I've learned alot.
This babydoll is in danger of water intoxication. People actually die from this. Her little body can't handle that much water and what happens is water is like a natural diuretic and is actually pulling water out of her intracellularly and dehydrating her causing sleeping problems. An electrolyte imbalance is occuring. Dehydration is occuring intracellularly. The water is going right thru her, that's why she's peeing so much. She's actually getting dehydrated during the night, and recovering during the day and then dehydrating again the following night. Her thirst is not being satisfied, that's why she's demanding the water. She needs something with electrolytes, perhaps pedialyte instead of water at night. This will satisfy her thirst and she won't be waking up, wanting water and peeing all night.
I've included a link FYI.

I hope you get this message and apply it. It will work.
It has to.
