for 20 minutes alone to clean the bathroom, there is a wrong and a right way to buy time.
The wrong way...is to leave the finger paint-loving two year old alone with a yogurt snack. Although, her beautiful face and the sound of "Jesus Loves Me" sung to the beat of swirling, happy fingers isn't so bad.
The right way...is to ask the boys to recreate their history lesson with Legos. Not only will you get 20 minutes, but possibly an hour and 20 minutes. And afterwards, they will get the joy of reenacting the barbaric ways of the Ninevites leading the Assyrian army against the Israelites. And that will be a good show!
