Does her doctor know that at 6, she still is wearing the pullups at night? I know some kids have bladder issues, but it just makes me wonder because neither of my kids wore pullups at night after being trained for a couple of weeks. I limited their liquid, no drinks after a certain time, and they would wake up dry. My kids are 6 and 7, and in my opinion, not knowing any medical background about your daughter, I would just throw them out. I would tell her that she is held accountable from now on. Sure, you may have a few nights where she wets the bed, but after she has to get up, get cleaned up, change clothes, and HELP you make the bed, I guarantee you she WILL stop. You have to hold kids accountable, otherwise, why would they change? It's easier for her to just wear the pullups you are giving her because it keeps her from having to get up at night. See what I mean? You're enabling her. Both of my kids usually make it all night without having to pee, but if they DO have to pee, I hear them get up from time to time, go pee, and go back to bed. Your daughter is the same age, and she's peeing in a pullup. I'm not being mean, just trying to shed some light on it for you. Take all the pullups, get rid of them, and tell her that she's old enough to know when she has to pee, and to get up and go when she feels she needs to. If she wets her bed tonight, give her a laundry basket, tell her to strip her bed, have her go into the bathroom herself and rinse herself off in the bathtub, give her clothes to change into, and have her help you get the sheets into the washer. I make my kids accountable for things, like when they spill a drink, they clean it themselves.
I know you said she ws scared to get up and go to the bathroom, but this may just be an excuse. You could always leave the bathroom light on, that way not only will the light be on, but it will also flood into hallway. Don't give up after having a couple of wet nights, that will only teach her that she really doesn't "have" to not wear pullups. If she pees, mommy will give them back. Keep with it so she realizes that if she doesn't stop peeing in her bed at night, she's going to keep on having to get up and go through all the hassles that come along wtih it.
