We really went minimal after our fourth kid. Too many toys, too much of everything. We don’t need 3 whisks, or 4 blankets, or 6 duvet covers, or 4 spatulas.
We now have a fairly minimalist house, with the exception toys, but here we do weekly rotation, leaving most of it boxed up in the garage and only some out. They kids think they get new toys when some of their old stuff reappears.
