We got rid of the pacifier over the course of 3-4 days. Here's what we did: We cleared out every pacifier except ONE. With a big needle, we poked a hole in the tip of that pacifier. Our daughter picked up her pacifier, put it in her mouth, pulled it out and looked at it, tried it again, and demanded, "Paccie broke!" We explained to her that once you've had your first birthday, pacifiers and other baby things don't feel right anymore -- and it's because you're becoming a big girl. She didn't believe us.
The next day we took a pair of scissors and trimmed off the smallest bit from the pacifier. Again, she expressed disapproval with the pacifier, and we reminded her that she was a big girl now, and that soon she wouldn't want /enjoy the pacifier any more. She still didn't believe us.
For another day or two, each day we trimmed the smallest bit from the pacifier. On maybe Day 4 she found herself forced to hold the pacifier in with one hand, leaving only one hand free for play (she'd just had her first birthday, so she had cool new toys). She put it down and never asked for it again.
I highly recommend this method!
My dad was a pediatrician. He told me to watch my kids around one for a time period when they seemed less attached to their bottles and pacifiers and to leap on that moment.
Yes, around age one we took away our oldest's pacifier; it was a problem for a few days, and then it was over.
So thankful that we didn't introduce our twins to a pacifier but if we did I would have wanted them off by one.
Eh, you don't always get to choose. Our youngest wanted nothing to do with a pacifier ... but at a young age she sucked on two fingers (never a thumb). You can take away a pacifier, but you can't take away fingers!
