Play is essential to children’s development – kids learn about themselves and the world around them by having fun and taking risks. In some countries scientists have linked a decline in free play with a rise in children’s mental health problems. In this programme we visit a playground called “the land” where no parents are allowed in! This highly-regarded project in Wales now supports adults too, an approach dubbed “play-based community development”. Plus we visit a “soft play” centre in Los Angeles, USA, one of a chain of play spaces that have been created specifically for autistic children and their families.Presenter: Myra Anubi Reporters: William Kremer, Emma Tracey Producer: William Kremer Editor: Jon Bithrey Sound mix: Hal Haines(Image: Children at The Land adventure playground in North Wales, BBC)
