My 4 yo DD seems to loose it with anger regularly, something small (dropping her apple) can trigger her to scream with frustration. She says she is 'angry with herself'. Recently while she was in timeout she ripped apart a favouriter teddy bear! It hasn't happened for a little while, but she has bitten and pinched herself before. :(
Often, she looses it for really no reason, it will be something like putting her shoes on, dropping a pen, not being able to find the right doll, that starts it all off.
She makes this screaming / wailing / crying noise that is so awful if you heard it you would think she had seriously hurt herself. It terrifies her younger brother. (and me frankly). I talk to her all the time, ask her why she feels that way, and ask her to use her words to ask for help when she needs it etc, she can comminicate very well with words when she wants to, but her first reaction is to melt down with anger. When she is in control of her moods she is generally a happy, bright girl. Her pre-school have not reported any problems.
Is it normal? I worry more as I come from a family with a background of depression / mental health issues that there is something wrong.
