Confessions of a Frustrated Parent: My Sixth Grader Won’t Brush Her Own Hair!

At what point do kids start brushing their own hair? I have a kid going into the sixth grade who won’t brush her own hair. She sits around and lazily slings the brush through a little 1X1 portion of her hair over and over again not making any progress. She just watches me lose my cool with this stupid look on her face. Then the tears start. Three hours a day. Three hours a day just to brush her hair. I just flipped out on her five minutes ago, and I know she’s in there staring at herself in the mirror with her mouth hanging open. She’s not a stupid kid. She’s pretty darn smart, but I want to shave her head. That’s it. That is the solution. I’m going to cut her hair off right now.
