My husband sat next to a woman on an airplane flight. They got to talking about their respective kids... She had a son a couple years older than our daughter. She said something that stuck with him... "When my son turned 2, I took away the pacifier cold turkey... If I had to do anything over again, I would let him have it until at least 3. Because once he lost it, I lost all leverage (in regard to getting cooperation, good behavior, etc.); I no longer had anything that he really, really wanted."
With that, he has asked that we not forcibly 'pull the plug' until she's 3. Although she can't have it unless it is bedtime and goes the whole day at daycare (even daytime nap) without it.
I also noticed, when I tried to take it away when she was 22-24 months, she started sucking/gnawing on her fingers. I would rather her have the pacifier instead of redirecting the habit to thumb sucking--that is a much much harder habit to break. And I don't want her sucking on blankets as those are harder to keep sanitary, especially once the child has dropped or dragged the blanket across the floor.
