How do I get rid of my almost three year olds pacifier?

My pediatrician suggests NOT taking it away from him cold turkey because they use it for comfort and without introducing something else to them in its place it could cause mental anguish. My oldest son had his until he was 4 (yes I'm ashamed) but he had to let it go on his own. My 2 year old just got tired of it eventually and when I noticed him not wanting it as much I hid it. He still asked for it for I would distract him with other things until finally he forgot it about it which took a couple of months. Just give him time, he'll let it go when he's ready.
