I would ban carry on totally as a first step

I'd completely agree, except that then you'd be dealing with lots of angry passengers listening to screaming babies sitting in dirty diapers for hours on end.

Then again, I've chosen to stay off planes. Carry on. ;)

But for the 99% of passengers who are not taking care of young children, I suppose carryon could be banned. Then the airlines would actually have to feed us - what a concept!

" screaming babies sitting in dirty diapers for hours on end."

No problem, instead of a pack of nuts you'll now be handed an airline diaper, wipe and a flight tube of Diaperene.
