Hi, I need some support. I have a ten yr old girl and a 8yr old girl. The 10yr old lately has become very moody and when I ask her to do something or just in general try to talk to her she screams back at me. Also if she wants me to do something she demands it to be done right away, she will not leave me alon untill I do it.How do I get this behavior to stop and is this early for teen behavior? Thanks..
