I have flown cross-country with a toddler several times now. I know how difficult it can be, and how very, very loud it can be, even if the parents are doing absolutely everything in their power to be as respectful as possible of the other passengers. Which is to say: I am not an especially intolerant person when it comes to in-flight disturbances.
But OH MY GOD did the flight on Saturday ever make me insane. So I have a question for you, because I suspect that pounds and pounds of pregnancy hormones combined with the fact that I had just dragged unreal-heavy bags through an unreal-large airport makes the validity of my emotional response system a little…untrustworthy.
