Weaning help!!

Ladies my LO is 13months, and we have successfully transitioned to cows milk...I strictly breast fed for the entire year, and decided to wean...we are down to 1 time a day, which is at night...though some nights I can get him down with a bottle...now the BIG DIFFICULT is the middle of the night...he wakes several times still and uses me to nurse himself back to sleep...basically I am his human pacifier! He takes a pacifier through out the day, nap times, even at bed time...but If I try to give it to him in the middle of the night when he wakes, he screams...he’ll only accept the boob! Any ideas ladies? I just don’t know what to do!
