M.W.
I just potty trained my youngest who is 2 and I am not even worrying about nights because she just is not ready. My other two children were 27 months when I trained them, but they dry at night in their diapers first so I started that right away. Is she really wet in the morning, or just a little bit? What I did with my son to get him completely trained was I put one of those waterproof pads (or actually a couple of them) under him at night so if he did have an accident it would be on the pad, not the bed. It seemed to work for him. After only a couple of nights of peeing on it he stopped and hasn't wet the bed since. My son who is seven still has some friends that wear pull ups at night. Most of them have stopped, but up until last year most of his friends that would come for sleepovers generally had a pull-up.
