ds has had a personality transplant since he turned 3. Instead of asking politely for things hes started to scream at me for things and then scream even louder if he doesnt get his own way. He used to accept the meaning 'no' but now i get temper tantrums and him hitting me. He's just turned into a real screamer and seems to be giving attitude all the time.Hes refusing to go bed and then ends up sneaking into mine in the middle of the night. I really dont know how to handle him at the moment.His daddy is working away alot and obviously this has unsettled him-could this be an attention seeking?
