Yesterday she whinged her washing doesnt get done quick enough
In that case show her where the washing machine is and how it works
IF i were you as long as her washing is NOT in washing baskets i'd leave it, let it pile up til she has no clothes and tell her if it's not in the basket it's not getting washed, then say you don't care if she has to wear PJ'to school.

Good idea on getting DH in on it too, your not laying down RULES your discussing as a family how the house should run, keep it simple and just discuss what you expect from her
