My daughter has turned overnight from a lovely natured (most of the time anyway) child into a complete and total whingebag. She whines and whinges all day, and bursts into tears at the drop of a hat. I know it's normal for a child this age, but how do I cope with the perpetual whining and crying? Is there any way to distract her or stop this behaviour? We've tried ignoring it, but it just gets louder and more whiny and I think my head is going to explode!
