At What Age Should A Child Be Responsible For Cleaning Their Room

I am sure I should have started sooner making my daughter more responsible for cleaning her own room, she is almost 4. How can I make it her responsibility for the most part of cleaning her own room (picking up) with as little fuss as possible?

I started making my son responsible for cleaning his own room, and low and behold it does not get near as messy now days.

What I did was get it all cleaned up and organized to begin with. I also made sure that there was a regular place for everything so it made sense to him how to pick up and clean his room.

We went to the store together and bought a few storage containers and I let him help me decide which toys went where and gave his a little control over it. I told him that he should pick up each day but on Saturday he had to have his room cleaned up properly before he could watch tv or go outside and play.

Then for the first couple of weeks or so it was kind of fun for him and he kept it cleaned up pretty good and kept it organized. He then decided he was bored with it and didn't do such a good job and then when Saturday came it took him forever to get it all cleaned up and he wasn't really happy about it. He rarely lets it get to disaster level now and tries to keep things put away correctly.
