The document discusses StoryTime Effective Practice (STEP), an approach to planning storytimes that promotes child development across four domains: emotional/social, language/literacy, physical, and cognitive. STEP divides storytimes into parts that connect books, rhymes, songs and activities to developmental needs. Examples are provided for how to adapt elements like rhymes, books and flannelboards for different age groups from infants to preschoolers to strengthen skills in each developmental domain.
