With our first child, he brought them to school (he was older than 1) and gave them to the babies. We had arranged it with the school ahead of time and there was a present in exchange for the pacifiers from the babies.
Our second child, the exchange did not work as well. So, we cut off the tips of the pacifiers and he did not enjoy them as much anymore (though a lot more than I thought he would).
Our third child, they just disappeared one by one and we kept saying when they're gone, they're gone. He actually did really well with that.
Our fourth child never had a pacifier except to steal her brothers and chew on it. I find the faster you do it, the easier. I think the younger, the better. And, I think if you prepare yourself for a few nights/days to a week of 'difficulty' but ride it out, you'll be happy you did.
With our last child, I do things (take away bottle, stop night feeding, etc) 'abruptly' and she has accepted all of the transitions with ease.
Good Luck - it's not fun.
