I night nursed my daughter until she was 18 months and then decided to wean her. I continued to day-nurse her until she was about three years old. I ended up writing a children's book to help her night wean and it was very helpful. The book is called Sally Weans From Night Nursing ( on kindle and Amazon) and it helped her understand the process and reason for night weaning (basically sleep) so that I think it was a more gentle experience that she understood better. Hope it helps!
