Most miserable day of my life was sitting next to a young couple with a 1 month old on an 8 hour flight to Maui. The kid screamed the entire time. I drank 6 dewers and took an ambian and still couldnt sleep.
Why would you take a 1 month old on an 8 hour flight?
I'm guessing because a boat ride to Maui was impractical. This is one I have sympathy with people on. As long as parents are trying to calm their kid down and not just ignoring them while they act crazy, I don't get mad. I don't think people with kids should be banned from public transportation and a screaming baby is not as bad as a fat person spilling into your seat or somebody that hasn't showered. If we get serious about airline etiquette and start kicking people off for things like that, I might could get on board with banning babies because then banning babies might actually turn flying into a non-miserable experience.
