I made up this 'Sanity Recharge Station' out of a watch box and stuck a timer in it. Here's how it works. Your child/children will have to give you an hour (or whatever set time you want) without asking for anything. In the mean time, you can go have a quiet moment to gather your sanity so that you can be refreshed. The kids can see how much time is left by following the arrow, and once the goal has been met, they can randomly select an activity from the box as a reward.
