Linus

I have fallen in love with my train blanket. It used to hang on the back of the rocker in my room, but now, each time I see it, I have to take it around the house with me. Since it travels a lot now, it ends up in some strange places, and I think Mommy and Daddy try to hide it from me. But, I usually find it, and then I giggle and get excited because I have found my beloved train blanket.

Mommy and Daddy say that if they encouraged me at all, I'd become attached to this blanket as my transitional object, and soon I'd be like Linus. Does anyone know what that means?
