In Five Simple Steps
Step 1: send older two children away as a special treat with Daddy to visit overnight with Nanny and Poppy.
Step 2: put two younger children to bed for their afternoon nap
Step 3: Eat a whole block of DARK chocolate with bits of raspberry through it while you surf the 'net and otherwise procrastinate. You may feel slightly queazy toward the end of the block, but persevere. Reason that Beloved doesn't LIKE raspberries so it would be downright CRUEL to leave it and eat it in front of him.
Step 4: Get a sugar buzz/caffene high LIKE NO OTHER YOU HAVE EVER EXPERIENCED and clean everything in sight including the two younger children who have now woken up from their naps.
Step 5: By the time you have finished step 4 you will have fed and put the children in bed again as it will take a few hours, even totally buzzed. Wonder as you put your breastfed infant to bed why she is so chirpy and wide awake at bed time. Look around at a job well done and push aside the niggling temptation to go and get another block so you can get the kitchen/dining/bathroom area done too.
