Something like one in eight kids wets the bed til age six. So, Relax, buy a couple of those plastic sheet thingies and make the bed twice, then all you have to do at night is pull off the top sheet, and the plastic sheet. There's another blanket, fitted sheet and plastic sheet underneath. Also maybe put her to bed in just a t-shirt and panties so a quick change is easy.

This too shall pass.

edited to add... maybe since the "wet" sensation wakes her up this could be a training tool for her body. KWIM? Like letting a potty trainer go around in just underwear when you know he's going to wet so he gets the connection??
