My kids have a habit of leaving their dirty clothes lay in a pile on the bathroom floor when they are done taking a shower. I left them all week to see if anyone would take care of them. I am not surprised that they didn't - I am surprised that I thought they might. This week the laundry experiment is officially over.
From now on I will pick up their clothes each night and put them into the wash. I know this does not teach them responsibility. I know this does not teach them independence. I know this does not teach them consequences. And I'm ok with that. My oldest got home from volleyball at 9pm with more than 2 hours of homework still ahead. My second daughter went from her basketball game right after school to another practice, and she also got home after 9pm with 2 hours of homework. As far as teaching responsibility, independence, and consequences - managing a schedule like that trumps picking up their own laundry any day.
