All of my kids have something they drag around with them for security. For Zander and Sarah it's a blanket, for Brendan it's usually something that fits in his pocket or a picture of his dad. For Tanner it's an old ratty Spiderman pillow that has been sewn up several times. He thinks he's too old to carry around a snugly things or to sleep with snugly things so on Saturday mornings this is how I find him.
It isn't his pillow anymore, it's his hat.
