S.W.
I went through this same thing about 3 years ago when my son was that age. I finally put a drop of hot sauce on the nipple. ( i did check with his doctor before doing this) After a few nights when the bottle tasted yucky, he wanted nothing to do with it. Bedtime and naptime became a breeze!! Its worth a shot. I know other moms that just didn't offer it and listened to the screaming for it as well.
