DD (5) and DS(3) used to be much better at doing the day to day things that I expected them to do - i.e. getting dressed/undressed, allowing me to brush their teeth, eating at the table, and playing for maybe 10 minutes at a time without squabbling. But somehow, something has slipped and most of this is not happening smoothly anymore. They are driving me insane, not doing anything I ask (even after I give up asking nicely and start shouting), and squabbling constantly.
Please help me get some perspective with some suggestions for how to get back to some reasonable standard of behaviour...Please!
