My daughter is 4 going on 14. She has a very bad attitude and can be very bossy when it comes to playtime (and pretty much everything else). She also whines and SCREAMS her head off (really bad) when she doesn't get her way with tv time or anything else. If I tell her to do something nicely and if it's something VERY SIMPLE she refuses, argues (all the time for literally everything), screams, whines, etc. I try to give her a time out, but the only place would be her room where she proceeds to scream incessantly and bang things and throw things all over her room. I have to hold the door closed otherwise she comes out still angry and will bang things all around the house and slam doors. This behavior is TOTALLY unacceptable to me and her anger is out of control! I live with my parents and they are no help, in fact they enable her tantrums by responding to her disrespectful behavior and giving in to what she wants. They will even shoot me dirty looks standing by the stairs and my mom will try to get her out of time out early to "talk" to her which makes the tantrum worse. I feel like I'm dealing with a serious problem and my husband thinks I'm overreacting because she doesn't do this with him and he's the one who gets her to calm down eventually. What am I doing wrong? I have tried counting, time-outs, spanking, stickers, taking tv time away, etc. pretty much everything and she is still RAGEFUL! I feel like she hates me and my parents think that I'm being too harsh when all I'm trying to do is disipline her for her acting like a demanding BRAT! She literally will scream like a banshee if I say, "You can't have a cookie now, but you can have it after dinner." She also will never take a nap even if she is exhausted and will be tired and cranky for the rest of the day. How can I positively parent if I've used every parenting tool in the book? She is very smart (perhaps gifted) and will find numerous ways to disobey and disrespect me. Please help!
