When my kids were young, my wife managed our home using impressive lean techniques.$$ When we embarked on long road trips, we would always leave very early in the morning in order to get as far as possible while the kids were asleep.$$ In order for the kids to sleep in the car, we had to get them from their bed to the car gently, quietly, and rapidly. When done successfully, they would go back to sleep almost immediately. To facilitate this, she sent the kids to bed fully dressed in tomorrow$$s clothes. Shoes were put in the car the night before.
