Haha, I hope not. It really winds me up when people complain about kids in premium cabins. If they're babies, they might cry, and if they do, that's just fine, it's what babies do. Having travelled with our son from an early age I have the utmost respect for parents travelling with young ones now. Lugging everything around through the airport, cramming everything into your hand luggage that you might need, it's a challenge. The last thing you need is someone moaning after you've just ran a marathon obstacle course through the airport to get to your seat. It is the single reason we flew BA rather than budget airlines on numerous occasions, because they just make it easier. If there's any opportunity to make that trip easier, I say take it, and if that happens to be by using a premium cabin, if you're in a position to do so, do it.
