baby ONLY sleeps with bottle in his mouth

My baby boy turned 3 months today and the only way he falls asleep is by having his bottle in his mouth which sometimes causes us to overfeed him. He refuses to take any type of paci, my husband and I have bought any type of paci u can imagine and he just spits them out. Its getting hard and idk what to do to rid of this habit. Has anyone been through this, any tips?
