If schools become meal providers, what happens at holidays?

An interesting comment at Whale Oil:

As I was eating crayfish last night I was wondering who is feeding all those 10,000s of starving kids we keep hearing about who are living in poverty over this xmas New years break while the schools are closed?

I haven’t read any reports of them turning up in droves at A&E suffering from malnutrition …or are they only starving when politicians are not on holiday???

This highlights the problem of making schools responsible for feeding kids, rather than parents. What happens at school holidays?
