My family wants to do a youtube channel that would be aimed being educational for small children. Compilations of different animals and colors, etc. I know this has been done to death, with a lot of channels putting out VERY repetitious content. We want to make our channel more quality with more effort put in to our videos. I've been looking at different channels and i haven't seen ads or comments on any of these types of channels. Are these not approved for monetization?
