M.,
First, I attended a STEP (Systematic Training for Effective Parenting) class provided through FCPS. One of the things I learned was to realize that most of what my teen boy did was to elicite a reaction from me, even the negative reactions. I found the STEP program crucial to understanding my teen. He still drives me nuts but I have tools to try to communicate with him.
Second, in our house, I speak few words to my son in the morning. I don't engage in conversation when he says things like, "I hate school...This sucks...". Or when he grumbles all the way to the bathroom. All I say is, "The time is 6am. It is time to wake up." Then I walk away. I listen in the hall for noise to indicate he is up. I might say,"Get dressed in clean clothes" or "Brush teeth and use deodorant" But what I don't do is argue, no matter how much my son provokes me. It only makes me more upset and nothing good comes from it.
We have to do what works for our own families. You only have about 2 &1/2 weeks left of school mornings. Good luck to you.
