To reduce clutter of toys in the house, just get rid of some. Those that are outgrown or unused.
Because, "rotating" it, just retains the same amount, but it is elsewhere.
Same stuff just different places and taking up space in other places.
I don't rotate.
But we do get rid of toys/stuff, throughout the year. Periodically.
My son however, is good about "rotating" toys himself. Meaning, he has always played with his toys, and knows where it is, and will get back to many of them and play with them, still. Versus my daughter, once she's outgrown something then that's it. She's done. And then we get rid of it or often times will then give it to another family with younger kids.
But anyway, the only way to reduce clutter is simply to get rid of stuff.
Kid stuff and, adult stuff.
For example, if I tell my kids they have too many clothes, and it is no longer worn or outgrown, we get rid of it. Same for us as parents, WE have to do that, too. Not just my kids.
OR you organize it better, and then get rid of stuff that is just piling up for no reason.
I also don't rotate because, my kids have their own ideas of what they want to play with/use/have around... that is per frequency of use. And they will get it, they know where it is. There are certain places for certain things, in the house. My kids have THEIR own ideas, of what to play with or use. Thus, I don't rotate. There is no need to.
