So I'm currently staying with family, and my 12 year old cousin is... Well... A brat. I feel so bad for my aunt and she keeps asking me what she should do because she feels she's tried everything. I'm at a loss because I'm only just expecting my first. So every single day since I got here (yes every day) her daughter throws the biggest tantrums I've ever seen. She screams at her mom that she hates her and wants her to die, slams doors, says she's going to run away forever. She has boundaries issues, such as unlocking the bathroom door and walking in on her little sister using the bathroom, and going in her parents room without permission. She has this sense of entitlement like every one owes her something just for being alive. She is very nosey and her attitude isn't limited to just her mom. She does it to me too but I always just walk away. It's weird because her sister is nothing like this at all, though I get she's not a preteen yet. It frustrates me because her mom is SO good to her. They have nice things, their own rooms, she takes them to do fun stuff fairly often such as swimming, she cooks homemade dinner every night, and packs their school lunches every day, they have tons of clothes. Basically she doesn't realize how good she has it. She says she wants to be out in a foster home HAHAHAHAA. Her mom has tried talking to her about how she's feeling, she's tried "natural" consequences such as if you don't take care of something you lose it, etc; etc; half the time I don't even know what the kid is hollering about. It seems she just enjoys fighting. Last night she tried to start a fight with her mom and she just went in her room and shut the door, soon enough her daughter is outside banging on the door screaming I HAVE TO TALK TO YOU RIGHT NOW!!! Anyone have any advice?
