"Mommy, you're supposed to do おにぎりすわり when sensei reads a book." This is what my daughter told me yesterday when she was pretending to be my sensei. The "suwari" means sit, and onigiri means ... onigiri. She showed me, and you're supposed to bend your knees so they make a triangle, like a typical onigiri shape. Cute! But my legs are pretty long, so it's a little uncomfortable. Oh well.
