My son would not take one after his birth, my hubby and I were at odds about it, but later on, we would give him one at nap, or bed time, and it helped him settle. He was never dependent on it. As soon as he was settled we would remove it, and therefore it was not something that he had access to. Basically, we would use it in an emergency......then take it away when it worked!! It was a cinch to wean him from, I spent a week in Florida with my hubby's family, and took it away then. As opposed to myself........I had one til I was three, and my older brother and sister would take it away from me, hide it, and say.......'where'd it go??' so, that's what I learned to call it, my where'd it go.
