How to break a baby from a pacifier?

My son is 15 months and is very attached to his binky! It helps him to fall asleep at night, which is why we’ve allowed it so long. During the day he doesn’t use it as much. I’m afraid it’s going to affect his speech if he keeps it for much longer. I never planned on giving my child one because of all the stories I’ve heard about breaking the habit but the nurses in the nicu gave it to him and he became attached! Lol. What’s the best way to get rid of the binky?! 🙄🙄
