My daughter had a visit from the "paci fairy" on her birthday. It was a mark of growing up. It was difficult for a couple of days but by the end of the first week, it was a done deal. My girlfriend used the "paci fairy" for both of her daughters. The first was a breeze, the second more difficult. All of the pacis were gone and a simple conversation reminding them that they were too big and the fairy had taken them (to a smaller child or whatever you want to say) help. As i stated, my girlfriend's youngest was very difficult, but within 1-2 weeks, she too was broken of the habit. It is hard on the parent and requires that you stick it out, despite the tears and tantrums. Good luck!!
