I tried SO HARD to get all 3 of mine to take pacifiers and none of them ever did. In the first few months of their life I was so upset they wouldn't take one... but once they got a little older I was so glad. If they don't ever take one, you don't ever have to wean them from it!
Oh well, it had it's uses! Unfortunately the use my little ones sometimes had for them was as a projectile.
