Children's right to play is formally enshrined in Article 31 of the United Nations Convention on the Rights of the Child (UNCRC). However, few research studies have explored children's experiences of play from an explicit rights-based perspective. Using children's views to illustrate the multi-dimensional relationship Article 31 holds with other key children's rights, this article shows how a rights-based classification of play emphasises issues such as freedom, safety, choice and inclusion. The article highlights the fact that while Article 31 has provided an impetus for play policies throughout the UK, these have not been developed from an explicit rights-based perspective. The article concludes by suggesting that the Committee on the Rights of the Child could take a greater lead on this issue through more robust monitoring and enforcement of Article 31.
