You love them. You just can’t be the entertainment every minute.
Dinner needs cooking, the meeting can’t move, and it’s raining again. You suggest the LEGO, the books, the drawing things, and ten minutes later they’re back asking what to do, or asking for the tablet. The tablet works, which is why it keeps winning.
Most alternatives hand the job back to you. Board games need a second player. Crafts need setting up and cleaning up. Worksheets feel like homework, so you end up coaxing them through every page.
These cases are built for that moment. You print one, they get a mystery they want to solve, and the hints on the page mean “I’m stuck” doesn’t have to mean you. They read, notice details and reason their way to a culprit while you get on with your thing. It’s quiet time you don’t have to feel bad about.
