sleeping and eating

Shelby

baby boy is 8 weeks old. I am breast feeding and I usually nurse him to sleep. I've been reading that i probably shouldn't be doing that. Is there an easy way to break that habbit? Tell me your experience! Also our nursing sessions havent been as long as they usually are. His diapers are still good. they look good and hes having the same amount of wets and dirtys. is he just filling up quicker?
