I think you might be right about the nursing thing, it sounds like he associates falling asleep with nursing so you might want to try getting him to associate something else (my ds sucks his thumb, but maybe a pacifier or lovey would work?) I would try rocking him to sleep rather than nursing and try to eliminate the nursing right before sleep-especially for naps and at bedtime. By the way, if I go in when my ds is fussing to reassure him he just loses it and wants to get up-that never worked for me either. Good luck!!!
