DD1 (6) left school throwing snowballs - she hit DD2's wee friend in teh face, then me and then put ssnow down the back of DS (2). I was so cross i put a lump of snow down her neck so she knew how horrible it felt - i felt awful immediately and apologised straight away. However she threw a total strop and tantrum ending in her smashing the stained glass window in our hall. she's upstairs now, what to do next? help please...its been a rubbish day.
