Does anyone have any advice or can recommend any useful literature about how to deal with my 7 year old's temper tantrums. She will sometimes have one when she doesn't get her own way and she knows that it is unreasonable but she can not curb her emotion. She only has them at home and not at school. I put her in her room to calm down but the other day we were on the drive and I had nowhere to put her, I didn't know what to do.
It breaks my heart 
and it clouds the very special times we have together (I am in a co parenting situation) I just want to make the most of every minute we spend together.
