In the first decades of the 20th century, many Scottish children lived in poverty, but enjoyed the freedom to roam as far as their imagination and the local trams would take them. A century later everything has changed. Most Scottish children now live in comparative comfort, but many are virtual prisoners at home, travelling outside only with parental supervision. We meet men and women who grew up in the 1930s, who remember playing games in the streets, camping out in the hills. We also visit modern families where the children play only with their tablet computers. This is the story of the world Scotland created for her children and how children reacted to those new worlds. Moving on from the infamous Victorian slums to the new town landscape of "Gregory's Girl" and then to the green, traffic-calmed suburbs of the present day.
