My DS is 11. Most of the time he is great and so loving. Lately however he has started to hurt his younger brother (8). He talks to me at times like I am something he has stood in and when he has done something wrong it is "never my fault". He has no respect for teachers..today telling me his year 6 teacher is a prat and then having no understanding when I try to explain this is rude. He constantly asks for new stuff and never seems happy with the things he has (he bought a bmx AND ipod touch with his birthday money in December). Its like he has no respect for me , his brother, his teachers or even his own possessions ( if something breaks he assumes it will just be replaced). I dont know what to do with him. I am banging my head against a brick wall..this has been going on for weeks and weeks now. Any ideas anyone????!!!
