After much weeping, wailing, and gnashing of teeth the family room was cleaned. What should have taken an hour or so to do took part of the preceding evening plus all morning. The deadline was noon after which I was going to gather up all remaining toys and give them away. Daddy took pity on the kids and assisted them so that they were able to meet the deadline. Mommy was a bit sad that she missed out on getting rid of toys who's only purpose is to be scattered all over the floor.
Previous to the cleanup you could barely see the floor. It is hard to decide if nagging them constantly to pick up after every toy they play with is worse than the massive amount of nagging I have to do to get them to pick up their own toys after a few days of letting things slide. They are more than happy to pick up baby toys or even help pick up other things, but the second I ask them to pick up a toy they have played with it is the end of the world.
