I was the same when DS became dry at night and wasn't sure what to do. I think you need to take that leap and take the nappies off. It's all still a learning curve and I am sure she will still wet every now and then. DS is pretty good now and only wets when he hasn't been to the toilet immediately before going to bed or if he is really tired. The nights where I *think* he will wet I cheat and pop a nappy on him to save the stress. So maybe give that a go if you feel comfortable.

Good luck!
