In my opinion, badly behaved children on aircraft be treated the same as badly behaved adults?. The only difference being, that as most of these children act this way because they've never been taught how to behave properly, and their parents don't give a sh1t about the other passengers, any disruptive action should result in the parents (and the children) being refused a business/upper class seat in the future.
I've ocassionally had to sit beside people who have very young children or babies, who often scream or cry, BUT, whilst this can make for an uncomfortable flight, this is not what I am refering to. Crying (and puking) by babies is normal and can not be avoided.
The majority of children I've ever encountered on aircraft, are usually very well behaved. Surely if some can manage it, it wouldn't be too hard for all of them.
