This literature review provides strong evidence that playing is central to children’s physical, psychological and social well-being. Whilst playing, children can experience real emotions, create their own uncertainty, experience the unexpected, respond to new situations and adapt to a wide variety of situations. Play enables children to form friendships and attachments to adults and to places, allowing for the development of familiarity and intimacy with both. It can provide opportunities for independent learning and building confidence, resilience, self-esteem and self-efficacy (Lester and Russell 2008; NICE 2010; Coalter and Taylor 2001). Whilst play can bring families closer together, strengthening parent–child relationships.
