Parents/Guardians are responsible for the welfare of their children at all times and as such are best placed to decide what level of supervision is right for their child and at what age they allow their child to play independently within communities.
In addition, an essential factor within a Play Street is to ensure the safety of children and communities at all times when they are using the streets as shared spaces, which involves communities working with their Local Governments to create safe environments.
Safety is paramount always.
