I tell my kids that nobody is their authentic self on camera. Everyone is acting to some degree. They watch YouTube sometimes and we’ll talk about what the purpose of the video was. Was this person trying to sell you something? Teach you something? Make you believe something? Right now we only have YouTube accessible on the living room TV so that I always know what they’re watching, but I won’t be able to control that forever so I am making sure they learn to think critically about what they’re watching. I started when they were toddlers by making a big show of not liking ads.
