Start by sending three of them to school, two for their last day of Kindergarten and one for 4-1/2 hours at Cottage. Make sure no one has a nap.
Then provide six hours of constant play including …
And playing school.
Not to mention, swinging, bike riding, scootering, playing house, etc.
It is advised to provide snacks, preferably on floating tables.
Make sure they have plenty of time to formulate and execute plans.
Then feed them dinner and drive them around until they pass out in the car. Voila!
