My dd started school a few weeks ago and is doing fine there - teacher says she is totally helpful and lovely in class. At home she has transformed into 100% monster . She has had her moments in the past but generally she has always been a sweet, affectionate, kind, helpful child. In the past week she has ripped a hole in the new carpet, written on furniture, hit and kicked me, pulled wallpaper off, fought wih her little sister. She has been having huge wailing tantrums and laughing at me when I try to do anything to manage her behaviour. Help! Don't know how to deal with this. I know that she is tired but she refuses to go to bed in the evening. It is all so out of character. She says she loves school. Should I try to ignore, or get tough? Will she calm down???
