DD broke something of mine today, not on purpose and doing something that really should not have broken it.
I exclaimed, " oh [DD nickname!] Go and get it!" She brought it to me and crossed her arms, head down, said "I'm not [nickname], I'm nothing!" I held out my hand, said come here DD, she repeated "I'm not DD, not Nickname. I'm nothing." Refused to look at me or come to me. After a few minutes she took my hand I'd been holding out to her and said sorry. I thanked her for saying sorry and told her I wasn't annoyed because I'd rather it had broken when she was playing with it than when I was using it as it could have caused me to have an accident.
I have no idea where this has come from. Its the second time she has reacted like that, after I told her off for being unkind to her brother.
I'm not sure how to deal with it. I've told her its ok to make mistakes, apologise and learn from them. That she's still little (she's 6) and still learning. That she will always be DD, she is not nothing etc
Is this type of huge over-reaction normal for children her age?
