A little project to keep them entertained was just the answer (and peace) we all needed. They worked together beautifully (with a little of mommy's help on the cutting part) creating a house out of cardboard boxes. And when the disagreement came about whether to use a certain piece as a garden or a roof, they worked it out and decided on a green roof! They got straight to work "planting" grass, strawberries, and flowers!
And when the work became too exhausting? No problem. A little rest on the outside porch gave them the boost they needed to continue their labor.
