My son spends about an hour getting ready for school every morning. He won't get up, I spend my time going up and down the stairs shouting, it puts me in a bad mood for the rest of the day and I get absolutely no work done. Then I can't concentrate because I'm so mad. He doesn't care how many detentions he gets for being late. I'm at my wits end. How can I deal with him? How can I stop it affecting me.
