My kids don't sleep. I mean they do, at some point. But there are definitely nights where I believe they will never fall asleep. All of my daughters share a room, so every night is like a sleepover. Which I simultaneously love and hate. I love it, because it's exactly what I wanted when I was a kid, but never had since I only had one brother. I hate it, because then I'm constantly hearing my daughters talking to each other, which means they are not asleep. Which means they will not be going to sleep anytime soon while one of them is talking and possibly keeping the others up. On the other hand, my son, who does not have anyone to share a room with and should therefore be able to theoretically go to sleep at a normal time, does not. He is his own keeping himself up, making up stories to himself, playing with toys in bed, even just lying in bed and staring at the ceiling. He is a night owl. To be frank though, they all come by their night owl personality honestly. Both my husband and I are and have always been night owls. Guess I'll just learn to live with it.
