As someone who was on the other side of that growing up, the worst thing you can do is see them as you seem to. I promise they don't mean to do this. They're a child. They are literally doing the best their knowledge and experience has prepared them to do with something their brain is doing to them that they don't understand and didn't ask for, and having adults take the frustration out on them will only make it worse. You might think you don't let it come through in your interactions, but I guarantee they'll pick up on it if you don't change your attitude.
