Compensation is fixed by distance, not by the ticket price, and is paid per passenger, children included. It is not due if the airline proves extraordinary circumstances. Whatever the cause, from 2 hours’ delay you are entitled to care (meals, drinks, a hotel if needed) and, after a cancellation, to a refund or re-routing.
