Is anyone else's LO dependant on the breast?

I am very fearful that DS is super dependant on my breast. He still does not STTN and will only sleep if we co-sleeps at 9.5 months. When he night wakes, I've been trying to soothe him in other ways besides automatically offering the breast, but after so many minutes, hours, of tossing and turning, I end up giving in and nursing him back to sleep. This makes me SO nervous for weaning, amonth other things.

Has anyone else delt with similar issues? How did you wean your LO? What methods did you use to soothe a boob-dependant baby?
