Using this backpack is a breeze. First, if you want to use it in the car, secure it to the back of the car seat. Then, place your tablet in the pocket with the clear window so you can watch shows or play games. When it's time for activities, unfold the tray. You can use it to draw, write, or eat snacks. The fold - down pockets are great for keeping your water bottle handy and storing small things like toys or books. As for maintenance, make sure to wipe it clean with a damp cloth regularly. Don't use harsh chemicals as they might damage the polyester and nylon lining. Also, avoid overloading the backpack to keep its shape.
