Something more than scribbles

My son has never been a colorer. I hear stories of other people's children who sat in their highchairs at 18 months and colored while mommy made dinner, not mine. He's been running since 11 months old with not a lot of interest in coloring except for a few minutes here and there, so needless to say that I was almost in tears when G drew this for me during our "iced in day" out of the blue. It was something more than a singular scribble on a page or EVERY color in the crayon box rubbed all over the page to where everything is black.

A pretty, pretty rainbow!
