Article 31 of the UNCRC says that children and young people have the right to have fun in the way they want to, whether by playing sports, watching films, or doing something else entirely. They have the right to rest, too.
Children and young people should be able to take part freely in cultural activities, just like adults. The government should make sure it’s easy for them to do this whether or not they have a disability.

The Committee on the Rights of the Child has produced many General Comments that help people understand how the UNCRC works in practice. General Comment 17 is about Article 31 specifically.
