O.H.
You can't entertain her and keep her happy 24/7. My mom always tells my kids, if you're bored, that's on you, you need to do something about it. Give her a day to relax and then don't let her start complaining. When my son does this, I tell him to go lay down until he feels better because he's making me sad with his whining and complaining. Then he usually finds something to do. My 13 yo dtr will be home with me this summer and I already told her we are going to be cleaning, cooking and learning things together. She is actually excited about it. I even told her I'd get the Just Dance games for Wii so we can get some exercise (we are in AZ so it will 110 outside). So maybe find some things you can do together also. But really, life is not always exciting and she is beginning to learn that on her own. Good luck.
