M.T.
Don't wake her up to pee at night. Night "training" isn't about waking up to pee, it's about the bladder maturing to the point that it doesn't need to be emptied at night. You are "training" her to continue emptying her bladder at night. If she wets the bed 3 nights a week, that's pretty much half the time and I'd insist on goodnights - if she's peeing anyway, it's really not any more mature or less embarrassing to pee through your pajamas and on your sheets and need mom to help you, then to pee in the goodnights and be in charge of changing herself, which at 5 she is certainly capable of doing.
Good luck
