V.B.
Although my daughter was about 3 when we did this, it really worked. We gathered up all of the pacifiers in the house (we had about 5), put them in a ziplock bag and took her to Wal-Mart. We let her pick out a toy and when we got to the register, my husband stood behind us in line and she and I "paid" for our purchase with the pacifiers and then I took my daughter ahead while my husband actually paid for the toy. We made a really big deal out of it before we went and told her that she was going to use her pacifiers to buy a toy. She asked for the pacifiers a few times at home afterwards, and we just told her "Remember, we used them to buy your toy" and she was fine.
