do all the school uniforms on day one. Make sure they're washed, dried, mended, folded and put away before dinnertime.
Now keep the kids in the same pair of pyjamas for the rest of the holidays. (a daily change of undies and socks will be required).
Wash all the socks and undies on the last day of the holidays.
NOTE: this will only work if you don't have to go anywhere. If you have to go somewhere, see step 4.
3. TIDYING ROOMS
Rule 1 is that every time the words "I'm bored" or "She's BREATHING on me!" or "That's MINE!" are uttered, all the children have to go pick up and put away 10 items.
Rule 2 is that apart from tidying, and sleeping, the children must play outside, on a 3 feet square piece of driveway, with one rubber ball, all day.
If it's raining, so much the better. Throw them a bar of soap.
Arrange to have a friends' kids one day, while they have yours the next.
Make sure your kids go to the friends' first. When it's your turn to reciprocate, say your kids have headlice. Glare at the other parent as though it's her fault.
NOTE: make sure you arrange this with a different friend each time.
teach the children to make Vegemite sandwiches. Let them eat all the sourgrass they can find. If anyone queries this, say the children are going for a cooking/foraging badge at Scouts.
NOTE: make sure the kids know some version of dib-dib-dob and can throw gang signs that look like Scout signals.
Using these handy tips may help you get through the holidays. If not, please address all complaints to your husband. It's his fault, too.
