I night weaned many months before my son stopped nursing completely. Since he was over a year, I did not feel I should have to continue "on demand" nursing. My son still nursed every am, afternoon and bedtime for about 6-7 months after I stopped nursing him at night. Is your daughter actually drinking at night? My son was not. He would latch on and pass out. So for about a week when he woke at night, I comforted him in other ways but just stopped offering the breast. He was mad at first but got over it. It is worth a shot. If you don't want to wean completely, you should not have to. Good luck.
