Cold turkey worked for us over a weekend.
I was gonna try cold turkey but have it as a backup if it didn’t work. My daughter actually lost her paci and when she would ask for it I would just tell her you lost it. I don’t know. Took about a week and half for her to stop asking for it. I also started to only give it to her for naps and bedtime. Then went for only bedtime. So that helped a lot. You can also punch some small holes in the paci so they aren’t getting that satisfying sucking and they might just stop on their own
I was going to try weaning but discovered cold turkey worked when my son would start looking for it I would say "it went bye bye" or act like it was lost we couldn't find it and it eventually got to a out of sight out of mind type thing
