How do you keep a toddler busy during a flight so she won't run back and forth to and from the lavatory?

Gabi kami nalipad 🤪 so they are tired and they’ll sleep kapag day trip i keep them occupied with lots of art materials one of my kids was diagnosed high risk sa adhd so when we go out of the country i make it a point that we have things that he loves.. i also talk to him alot during the flight..
