It is hard for so many reasons...
As a teacher, my first inclination is to tell my child's teacher how my child learns best, but instead I keep my mouth shut.
As a teacher, I know what classroom discipline techniques work best with my child, but instead I let her learn.
As a teacher, I need to be careful not to overstep my boundaries.
As a teacher, I can't let my child see my worry when he is struggling. I just need to work harder to support my child's teacher at home.
As a parent, I know too much because I am a teacher.
As a parent, I know nothing, because according to my child, I am not his teacher!
