Miri likes drawing. By "drawing", I mean she requests us to draw things and then she takes a pen in her tiny little hand and draws little bitty squiggles all over the paper.
Sometimes these squiggles are used to fill in faces on the people she requests (always "Niko! Mama! Dada! Mee-um!")
I'm not sure if these squiggles are meant to me in imitation of writing letters (which I suspect), but they certainly are created carefully and in great abundance.
