Sunbeam kit.

My sweet Kitty girl started sunbeams. After a little anxiety and reluctancy to let her leave nursery she has grown and matured and proved her worried mama wrong in almost every way. We're still working on staying seated. The boys keep me posted and the last report from Lewis was that "she still gets up and walks around, but she'll get the hang of it".
Could there be a more perfect word for three and four year olds than "Sunbeam"?
She is such a light and a joy.
