I suggest that children should not be prevented by the site management from having and working their own plots unsupervised if that is what their parents consider appropriate.
I think you are assuming that all parents are sensible and realistic about what their children should and should not be allowed to do.
Unsupervised children pose a site-wide issue. The child may be the only person on the site at a given time and there may well be safety issues to consider as well as the occasional ill-behaved child.
I am uncomfortable with the idea that I (or for that matter anyone else) am batter qualified than the parent to make that decision.
Squash, I wouldn't expect many six-yearolds to be responsible enough to work an allotment on their own, but at 17, or 16, or 14, or 12?
