Hi N.,
My 5 year old still wears pull-ups to bed too. We do make sure she goes potty before bed and sometimes she wakes up dry, but sometimes she doesn't. We give high fives when she wakes up dry, but I never act angry if she is wet. I know what she's going through.
I too was a bed wetter-until I was 6. My problem was physiological and I had to have a medical procedure to fix it. However, I think I also had a problem with just being a deep sleeper because I never felt the urge to go at night and would wake up wet. My mom was pretty understanding, but my stepfather at the time was not, so I felt a lot of shame and anxiety about it and most certainly would not have been doing it if I had any control over it. No kid wants to sleep in a puddle of their own pee!
My theory is that with small children, 2 and 3 year olds who are learning to be potty trained, waking them up to go and some of the other tricks may work because they are learning to listen to their bodies. I think once a child is a little older and they are still having the problem 9 times out of 10 there is another issue and these methods don't work. Waking them up in the middle of the night is just disrupting your sleep and theirs, so you might as well just stick with the pull-ups until they grow out of it and let everyone have a good night sleep and save on some laundry detergent.
I have a step-sister who wet the bed until she was almost 14. They tried everything, including the alarm that woke her up when she was wetting... which she slept right through. Finally, a urologist subscribed her a medication that worked. She is 18 now and hasn't taken the medication for a few years. Talk to your doctor, but I think most of them will say that 5 is still young and they may just tell you to wait it out a little longer. A lot of kids will just grow out of it with no intervention. There must be some little part of the brain that takes longer to develop in some of us... but it eventually does. I haven't wet the bed in years! ;-)
Good luck!
