L.M.
My son loved his and was hard to break but was done completely around 14 months (from a year to then it was at nap or bedtime only). But to hear my sister tell it, he was over 2 or 3. He was big for his age and I think she forgets that he was that big at 12 months.
My daughter barely took hers and weaned herself by 8 months.
I know a woman whose youngest daughter had her pacifier after her 4th birthday. Even with it in, you couldn't understand her speech because she always had it in and it afffected her speech horribly. Even when she didn't ask for it, her mom would pop it in her mouth. I hated to see it. I don't know when she stopped because I wasn't around her after that last sighting just after the 4th birthday.
