My friends son refused even at three to give up his pacifier, he was here playing one day and I told him I would get him this really cool big boy race car if he threw his pacifiers away. He walked over to the trash, threw them out and was done! He asked for it a few times, but never got upset as he was proud to be a big boy.
For a 14 mos old, cold turkey is the best method because he won't understand the other stuff. If he looks for it say "all gone"..and just let him fuss a few times. Seeing his dependency is only at naptimes then it probably won't be a big deal. Get him a new lovey, new stuffed friend to replace the comfort factor for him.
For the little boy I watched she did it on his second bday, making it a HUGE deal he was a big boy now and it had to go bye bye to new babies since he wasn't a baby anymore. That worked for them.
You are smart in doing it now as it gets harder to break habits like bottles and pacifiers with every month they head to two!! :)
