I have a very stubborn five year old daughter and she loves to push buttons. Lately any time I or her father tell her to stop doing something, like running in the house or jumping on the couch she will either just ignore us completely or start whining. She gets so many warnings before she is sent to her room, where she will scream until she is sick or falls asleep. She has tried this screaming fit in the stores to get what she wants and I just ignore her, usually she will stop but its ridiculously embarrassing and I cant always just take her to the bathroom or walk out of the store. I have tried the time out chair, she screams until she gets sick ( thats when she started going to her room) I have tried spanking, no amount of spanking works on her. I have tried talking to her and reasoning it out and she acts like shes listening but then will start the same bad behavior with in ten minutes. This is getting ridiculous and hard to handle when I have a 2 month old baby and I am trying to get a home baby sitting job, but want to get her back under control. She only started this behavior when she turned five. its like a switch went off in her head and she turned into someone elses child. I have bipolar, Borderline (BPD) and Manic depression and I'm hoping this isn't an early sign of the bipolar. To me it seems like shes having a hard time expressing her anger, I need help finding ways to help her express her feelings better. Im lost.
