Weaning ..

My son is just about 15 months old and I'm ready to stop nursing.. He is getting so rough pulling away and biting.pretty much have him down to 3-4 times in 24 hours but ready to go the rest of the way. He eats great and takes a sippy cup perfect.. He will just look at me and scream loud as possible she he wants to nurse. I try snuggling and rocking and soothing him but he will just bite whatever is close (shoulder, arm ect)

HELP!!
