For more than 50 years now, we in the United States have been gradually reducing children’s opportunities to play, and the same is true in many other countries. In his book Children at Play: An American History (2007), Howard Chudacoff refers to the first half of the 20th century as the ‘golden age’ of children’s free play. By about 1900, the need for child labour had declined, so children had a good deal of free time. But then, beginning around 1960 or a little before, adults began chipping away at that freedom by increasing the time that children had to spend at schoolwork and, even more significantly, by reducing children’s freedom to play on their own, even when they were out of school and not doing homework. Adult-directed sports for children began to replace ‘pickup’ games; adult-directed classes out of school began to replace hobbies; and parents’ fears led them, ever more, to forbid children from going out to play with other kids, away from home, unsupervised. There are lots of reasons for these changes but the effect, over the decades, has been a continuous and ultimately dramatic decline in children’s opportunities to play and explore in their own chosen ways. 

Over the same decades that children’s play has been declining, childhood mental disorders have been increasing.
