Children rule, and if you ever get the opportunity, you should absolutely play role-playing games with them.
I once ran a game of No Thank You, Evil!, the excellent children-focused hack of the Cypher system by Shanna Germain. Think Numenera, but you know, for kids! Everything basically runs off of three stats, which is great (except NTY,E! has a fourth stat that's all about helping out your friends, which is called Cool, which is the best thing). I was running for my wife, a D&D veteran at that point, and my daughter, who at the time was about 6 or 7.
They were in a combat with an evil witch, and my wife, who went first, didn't really know what to do, so she was like "I guess I attack it with my weapon", because that's what years of TTRPGs (and especially D&D) teach you. My daughter, on her turn, decided to try to run in circles around the witch incredibly fast in order to make it dizzy. It was awesome.
Always run games for kids, and whenever possible, always Yes, And.
