I found myself on my last two flights - the first to Chicago, the second to New Hampshire - sitting across the aisle from mothers with babies. Now, I love little babies. Except when they scream. Endlessly. In a small confined space. Within a few feet of me. God help, me I find it annoying.
There is nothing one can do, of course. I don't want the tiny tikes thrown overboard or anything. But it would be great if someone invented a muzzle of some sort. Or an incubator into which they could be placed while in flight.
Just some thoughts.
