Can You Hear Me Now?

What is with children and their hearing? Mine cannot hear a word I say. I will be speaking to them 2 feet in front of them and they carry on as if no one has said a word. Seriously. The do not look at me, nod their head or acknowledge me in any way. They just continue doing whatever it is I am telling them not to do. Such as, jump on the couch; climb up the banister; slide down the stairs; try to kill their sister; write on the walls; yell; scream or throw things. These are their favorite things to do, and clearly against the rules....more
