If you need a playlist to keep a child entertained (or an adult that loves Disney), try the Mickey Mouse shorts playlist here:
https://www.youtube.com/watch?v=x6AcuhX4ZUU&list=PLC6qIbU1olyXQe1WOKt8UJ4hErx3D7qt8 . It’s a set of 90+ short videos featuring Mickey Mouse and his adventures.
It’s quite fun to watch – I’ve been watching them with my nephew and I’m not sure which one of us likes it more!
