D.S.
What worked for me was the (we named the paifier binky) Binky Fairy. I maled a card to my kids with a note saying that since they were getting so grown up it was time for the Binky fairy to come and pick up thier binky to give to a new baby that is coming sonn and leave them a new toy for being such a big boy or girl. We made a big deal about the date in the card and the approach of the binky fairy just like it would be Christmas. Since a fairy is small we got a big plans and put christmas lights around it and put out a basket for the binky to go into. We practiced the binky in the basket for days at bedtime the binky went into it and and then magically on the date the binky fairy came and took the binky and left them a new toy in the basket.. We had no crying and the kids thought that every time they saw a new baby that it was thier binky making the baby happy..
Good Luck
