After a scuffle in the living room, Ethan approached me, crying. Simon, it seems, hit him on the head in frustration over a toy they both wanted. I disciplined Simon and told him to use his words next time he was frustrated - or to ask me for help.
A minute later, Simon walks in again and lays his head on my arm, "Mom, can you help me hit Ethan on the head?"
Good try, little boy.
