Am I weird for planning out my future children’s names as a teenager?

Ok so I, 15f, have always been obsessed with the idea of having at least one little girl of my own when I grow up, and I’ve planned out the names already. I feel like some people might think I’m weird for this. This one teacher said I was too young to be thinking about this type of stuff. Keep in mind, I’m not like in any rush to get married or have kids, I wanna have a successful career as a criminal or human rights lawyer, which I know is gonna take a long time. I don’t even think I would be a good mother, mind u😭. But lmk, is this like unusual in any way?
