Amy's awesome and cost-effective rainy day kit on Mom Advice reminded me that not only tires need rotation. Toys should be rotated too.
Before Ranger's birth, a friend advised me to rotate toys in and out of storage. She would put away toys when her kids' interests waned and pull them out a few weeks later to renewed interest. We adopted this habit with some of Ranger's larger playsets (a Little People castle which he peoples with pudgy plastic farm animals and a Weeble Three Bears set).
I really need to start thinking about toy rotation more now that our house's shared spaces teem with toys that only receive minimal play time. It's also a good way to filter out toys that are no longer age appropriate.
I'm drawn to Hedra's toy library concept at Parent Hacks although it requires organizing one of our house's black hole storage spaces.
