Based on the view that play builds the foundation for lifelong learning, this 3-volume set of videotapes (in English and Spanish versions) with accompanying facilitators guide depicts a wide variety of parents/caregivers playing with infants and toddlers to highlight the importance of playing and interacting in ways that support and expand children's abilities. The program, intended for use in parent or caregiver education, shows how childrens play grows hand in hand with their motor, language, and social development. The facilitator's guide offers recommendations for presenting the material and, for each volume of the series, describes viewer objectives, presents suggested activities and discussion questions, and includes photocopiable handouts summarizing information. Each videotape illustrates milestones for four developmental areas (social, language, gross motor, and fine motor) for the relevant age period, identifies activities and play that support growth in those areas, and highlights safety precautions. Volume 1 (24 minutes) of the videotapes is organized in two sections, corresponding to play from birth to 6 months and from 6 months to 12 months. Skills highlighted in Volume 1 include bonding, self-awareness, smiling, understanding words, lifting head, sitting, crawling, standing, climbing, and exploring objects. Volume 2 (18 minutes) focuses on play for supporting 12- to 14-month-olds development of gross motor skills (walking, pushing and pulling, climbing, kicking and throwing), fine motor skills (opening/closing, filling/emptying, arts and crafts, and sand and water play), language skills (2-word sentences, simple word games, books, and songs), and social skills (independence, pretend play, interest in other children, helping). Volume 3 (16 minutes) presents play to support 2- to 3-year-olds' gross motor development (running, climbing, jumping, playground activities, games), fine motor skills (puzzles, exploring how things work), language development (short sentences, stories, simple songs), and social skills (imitating, helping, pretending, and playing cooperatively).
