28. Play Dress Up
Have some old Halloween costumes from last year? Why not start a Dress-up time with your kids? Let them decorate and mix-and-match them. Furthermore, you can turn your living room to a theatrical stage and encourage them to act as their favorite character.
On the other hand, if you don't have any available costumes, try providing them some clothes from your wardrobe. Children usually like to play with their parents' stuff like heels, dresses, hats, and neckties. Add a little bit of makeup, too, if you deem it safe.
