Should noisy children be banned from public spaces?

The thought of well-behaved children playing quietly in the background is often a romantic image. The reality is often far from it. Many people find loud kids screaming and crying in cramped public spaces irritating.

But some initiatives announced this week may help to solve the problem. Budget airline Air Asia has announced quiet zones, from which children under 12 are banned, and a restaurant in the US has started giving a 4% discount to families with well-behaved children.

But do you think children should be excluded from certain public areas? Is it right for companies to offer financial incentives to families for good behaviour? And are loud children really that terrible?
