Whilst I agree that OFSTED has been rather clumsy here with this seemingly excellent Nursery/Kids Club, I am rather surprised those running the establishment were not aware of these guidelines.
They certainly aren't secret and even childminders have been aware of this sort of thing for years now - it doesn't take an awful lot to introduce some tweaks into the day to satisfy some of these rules.
Having said all that , the locals know how good the establishment is so I doubt they will lose any patronage.
