Hello,I have just registered in the hope that someone can help me with my four year old daughter.She is usually a well behaved child but over the last week she has turned into a monster.She is on antobiotics(the second lot in four weeks)so I´m hoping her being ill has something to do with it.She has become unbearable and would argue black is white for the sake of arguing.She never stops calling me,her dad and little sister names and she has become really aggressive, at times even hitting herself which really worries me.What do I do in this situation? ,I am a primary teacher and usually manage to cope with most situations but she has me stumped this time.I have tried various methods,ignoring and not rising to the bait,talking and reassuring her how much I love her even shouting when i´ve reached the end of my tether.Hope someone can help us .soon
