The Play Library is our collection of ideas for great toys grandparents can keep on hand so that they are always equipped and ready for fun. Toys that are open-ended and can “morph” for several different creative uses seem to be the best choice for a Grandparent Play Library because they encourage play that spans across cognitive ages, so they’ll be “in vogue” with children for a longer season. Sometimes, our collection will feature things that are not toys but should be.
