simply start giving it less. But be prepared for lots of crying.your baby got used to a pacifier and uses it as a confort tool. when my 4 month old daughter was 7 weeks we introduced her to a pacifier which i think was not good at all. Ayways i had her off of the pacifier when she was 9 weeks old and she hasn't used it at all since ad she doesn't look or ask for. It's going to take time but will happen. Good luck.
