I always like a good library day 📚
Get a large bowl preferably metal put all their small enough toys in it, fill it with water then throw it in the freezer. Let them get creative and figure out how to free their toys that'll give you about an hour😊 hope this helps
If you want some thing easy, try building a fort 😂. You don’t have to leave the house, and it teaches them to be a little bit more creative! (:
