Tired of 15 toddlers running in different directions when it’s time to move from play to lunch? The Trick: Blue painter's tape. I put "stepping stones" of tape on the floor leading to the sinks. I tell them the floor is "lava" and they can only step on the blue tape to get to their hand-washing stations. Total chaos level: Reduced by 80%. Bonus: It peels off the lino without leaving a residue. Try it today and let me know how it goes!
