We had a week of several storms in a row. So we bundled up to play in it.
Andrew eats and eats the snow. He even reaches down to others' boots when they come inside and eats any leftover snow that hasn't been stomped off. If he's not outside and the older boys are, he's at the window wanting to go outside. It's good to have several little pairs of mittens to switch out when a pair gets wet and cold.
And I have quickly learned that when Thing One and Thing Two ask me to help them build a snowman/fort/igloo, it means, "Build it while I watch you. And make it big."
