While I don’t think spanking is always wrong, I’m a big fan of time out as a first response. I put kids in time out when they need it, and the same for clutter. If one of my children has so much stuff that their things can’t manage to stay put away, I’ll start putting stuff in time out until the clutter learns to behave.
It’s amazing how quickly things tidy up when a favorite toy/sweater/whatever goes into a box for a month. It’s just like swatting one child, where the rest of the kids straighten up immediately. When you put a box full of stuff in the basement/attic/crawlspace/office/wherever for a month, the rest of the stuff starts finding its way where it belongs immediately and keeps that habit.
That said, I like this dad’s methods.
Today it would be a cell phone or an Xbox and it wouldn’t be nearly a month
