The one I call former difficult child is turning 12 tomorrow. I'm pretty sure she has been cheating on her diet and is acting like a difficult child today. I am very angry about this because I feel she made the choice to eat whatever it is and she knows it will make her like this. I've been trying to get her to do more to help around the house. By this I mean I want her to unload the dishwasher and pick up after herself and fold some baskets of laundry. I've put a password on the computer so she can't get involved in that until she does the 15 minutes of chores I want her to do. So today, as she sits there texting on her new cell phone, I tell her I am going to take the cell phone until she gets it done if she doesn't get started. She refuses to give it to me and goes in the bathroom, slamming the door. I'm not sure what she did in there but by the sound of it, some things might be broken. She's yelling that she hates me, she's staying in there until she dies, etc. She's also being very mean to easy child/difficult child who is chronically ill with something, laying around all the time, not playing with friends, etc. I told her if she gets 3 warnings, she will not get to have her friend sleep over tonight for her birthday. I do not want to have a friend here if difficult child is going to be defiant and rude to me and easy child/difficult child. She's already had the 3 warnings, 2 for being mean to easy child/difficult child, and one for the bathroom incident. I feel like just handing her her present tomorrow, making her cake, and going through the motions but avoiding her the rest of the time. This is mostly just a vent, I guess, but if anyone has any ideas about how to handle her birthday under these cirumstances, I would appreciate them.
