Funny how the boys' fighting inspires some creative intervention on Mom's part.
The boys were fighting over some ridiculous toy which Kiddo wanted to use as something over which he could jump. So instead I put a rectangle of tape on the floor for him to jump over. Now I call it the Amazing Rectangle. (This post contains affiliate links)
Things you can do with a rectangle of tape on the floor:
Jump over it.
Jump in it.
Jump around it. (Hi, downstairs neighbors!)
See how many times you can bounce a ball in it.
Race cars around it.
Race cars through it.
Use it as a start or finish line.
What do you think your kids would do with a rectangle of tape on the floor?
P.S. I highly recommend using low-tack painter's tape (test before use, but I've never has a problem.)
