M.M.
I have a 3 yr old little girl who loved her pacifier until she was about 30 months old. I was trying to potty train her and get her off the pacifier. You can't do both at the same time. So I got her potty trained first and slowly I took away the pacifier. First at nap time, then in the car when she got sleepy and lastly night time, which was the hardest. You can put her to sleep with it, but as soon as she goes to sleep, slowly remove it from her mouth and put it away until the next night. After about a week of that then trying putting her to sleep without it. They have to learn how to comfort and put themselves to sleep. Occasionally she will ask for it, but I just tell her that she does not need it anymore. Good Luck and I hope this helps.
