Are you sure this is water retention, and not weight she is putting on? Or even a belly full with as much she is eating given she is so skinny?
How does it feel?
She is soooo skinny, and things might look out of proportion for a little while until she gets her weight back...
I am just throwing another possibility out there - because she is eating a lot, and she is skin and bones... It might be weight coming back or a belly full...
You are paying a looooot of attention to her, and I understand your fears... She is doing so well, it might not be as bad...
