Need advice on taking my son's pacifier away?

Children and Babies alike use binky's for security reasons. Maybe you can substitute it with a "lovie". That's what I did with my son when he was 4 months old. I had the "lovie" smell like me and put it next to him at naps and bed. After a couple days he didn't care for the binky at all. Now he sleeps with his lovie every night!!!!!!
