School Holidays

Maybe take them off for a picnic for a half day?

I don't have any children by choice, but I remember what my mom did for us kids growing up. She'd make us an indoor obstacle course. It wasn't anything elaborate. She'd tie some string through the living room and have us shimmy our way through it to get to the other side. She'd also put down pieces of paper that we had to jump on in order to avoid the hot lava floor. It was lots of fun, and it allowed us to expand that excess energy. I hope you find something that works for you.
