Kids can find joy in the mundane, be it a cardboard box turned into a fort or a generic item from around the house imbued with possibility through imagination. When all that energy dissipates and it's time for a nap, you can make that more fun too with a home-made hammock.
As pictured above, you just need a large bed sheet that you can tie around the top of a table. This provides a place to sleep for a small child that's a bit more fun than heading off to their room and into their bed. Obviously you don't want to do this with a bigger/heavier kid, as the sheet can only hold so much weight. Make sure you test it for safety and don't tie the hammock too high off the ground.
