What’s wrong with me and kids?

So lately I’ve been wanting to be accompanied by children, toddlers, and infants. I’m only 16 so I can’t have one while I’m in school no matter the fever, but I need some advice or maybe even just a “diagnosis”. Is it bad that I’m ALWAYS wanting to me surrounded by children? That I want to watch the child grow up after raising it myself? I dunno. But I’ve never felt this longing before. It’s been going on for three months now!
