I make my 3 year old participate in cleaning up her toys. I always volunteer to help her, and we do it together. We do it consistently enough so that it's a habit, and she rarely complains. She visited her cousins recently and said, "those boys are very messy. They should clean up their toys!"

Most people, eventually, learn the value of cleaning their domicile (there are exceptions, of course).

I think parents live in hope that their kids can learn that value earlier than they themselves have, or at least help share their lessons learned with their kids - this is true of many things in parent/child relationship -> we want/hope better for our kids.

And let's not minimize the "I'm tired, I had to clean your room every night for the past 3 days/weeks/months/years/decades, you need to put some effort too!" aspect of course :->

It works various degrees of well or poorly with various kids, parents, and circumstances - like virtually anything else in parenting.

Maybe it teaches a recognition of pointless overhead and a healthy distrust of people who would fit in too well in Compliance departments?

Presumably you learnt that people will be unhappy if they're in a position of power over you and you don't do what they say.

Learning to clean. If you never did it as a child you would find that horribly annoying as an adult.

It was always easier to find the toy you wanted in a clean and tidy room.

Same thing applies as adults and non-toy items too.

I don't expect spic&span. The alternative is my kid can never find anything, because everything is in a pile on the floor. That's how you get ants (or worse).
