During the summer, the Rosemary Garfoot Public Library in Cross Plains, WI, holds one storytime each week which is open to all ages.  While planning and leading several of these storytimes, and observing others doing so, I became interested in the question of what the benefits and challenges of mixed-age storytimes are, and what librarians consider to be some of the best practices in running mixed-age storytimes.  Researching the question, it’s clear that there are challenges from the wide range of interest and ability levels, but that mixed-age storytimes can be a benefit to families, the children, and the libraries.  Best practices include being flexible, repeating items each week, involving caregivers, and using books and music in ways that will engage everyone.
