My 8 year old was the biggest sweetie for a long time. She used her manners, didn't complain often, followed the rules and never really fussed. But lately she has really been acting out. She loves kids,b but she doesn't like her little brothers and she has been acting totally out of character since they were born 2 months ago. Me and my husband thought, maybe she feels left out so we had become involved with the boys and have more alone time with her. It didn't work. She screams and whines about everything, she demands toys and if she doesn't get them (she never does when she acts like that) she carries on and on. One time during one of these tantrums she starting throwing things an pulled out some of her hair. It scared me really bad. Everyday these tantrums get more and more extreme. While i was writing this she throw a hard cover book a picture the was framed with glass and it broke. Is this just an extreme way to get attention? I'm making an appointment with her doctor in January. I have never seen her act out like this, I just don't get it. How does a child go from being a angel to a monster in 2 months? Any idea's or advice on handling this?
