Anyone see a pattern here?

Much to our amusement, our little bunny really likes to climb into (or be put into) small, cozy places.  Often she wants Anna to push her around while she's in the white bassinet or the red picnic basket. The cradle that she is sitting in with her best buddy Harper was made over 50 years ago by my grandfather for my mother when she was a little girl. It's still being put to good use after all these years.
