I just found this post because I searched momo in this sub haha. I'm 22 and work with children as well!! They're terrified of momo and it's basically all they've been talking about. Some are even scared to go to the bathroom alone. Usually things like this make me anxious to the point where I feel like I'm going to pass out, so I've been using humor as a defense mechanism and it's honestly been working so far. I keep making jokes about it and looking at funny memes. Like I saw a video of someone photoshopping it to look like an instagram baddie lol. It makes it less scary. Also do your research! I saw a few articles that talked about how it's actually a hoax. That kind of puts my mind at ease too
