When I was a little kid and stared at an older girl who already started to develop a figure, it was generally because I thought she was very attractive. Also depending on how she dressed, I might have been trying to look up a skirt or down a blouse or something.
I already knew staring was rude at an early age but I couldn't help it sometimes when I saw pretty girls. I was probably nowhere near as discreet about it as I thought I was.
So in my case, it was the opposite. I can't speak on behalf of other kids.

God only knows. They could be thinking anything in those little heads. Kids stare when taking in new information, a stare is just case of examing something. Seeing as they are young and not got as much knowledge as us it's probably them questioning something. Or wanting something. Or thinking of something completely unrelated.
