My 4 year old daughter has some major problems with her bahavior when she doesn't get her way. She always screams at us an constantly talks back. This is especially embarrasing when we are in public. She also hits us or objects around her when she becomes very enraged. We have tried numerous punishments, such as putting her in the corner for minutes at a time, taking away certain toys (or ALL toys) for the day), but nothing seems to work. Lately I've been threatening to throw away her favorite toys (and have with a few of them), but this also does not seem to work. She gets upset for the moment, but then quickly gets over it. She is SOOOO stubborn, and it is very frustrating. When we put her in the corner all she does is scream (extremely loudly) and cries. She's VERY dramatic. I tell her that she needs to calm down before I will let her out, but that doesn't matter to her. Please, we need help and her behavior is only getting worse. She rarely listens when I tell her to do something, and sometimes purposely defies me. My husband and I can't agree how to properly discipline her, and I know that doesn't help either. Other than this, she is an extremely happy child. We show her tons of affection and pay more than enough attention to her (she's an only child). Do we need to seek professional help??
