Ann Marie wants to be able to childproof her iPad for her grandchildren. Especially on YouTube. Leo says that there's a lot of sketchy things on YouTube that are aimed at children, that parents wouldn't want them to see. Fortunately, iOS has parental controls to prevent access. It's under "screen time." Go into settings, then screen time. She can then create a parental passcode and set up restrictions. Also, there are YouTube Kids, which she can give them access to, instead. But the best way to protect them is to sit them down and talk to them about what they shouldn't be exposed to. Teach them to be able to identify it and then take the action to get away from it. But parental controls are a good backstop.
