1. it's a bummer when kids act up whether in F or in Y. Flying ain't McDonalds.
2. nevertheless, parents should do what they can to avoid flying if possible with small children, and if they have to fly, to keep the kids entertained.
3. life includes kids. It might be better for others if babies, etc. would just disappear but of course that is impossible. We just have to live with it, it is an imperfect world where kids will fight, babies scream, etc., even in F.
4. I hate it also when kids act up and their parents don't do anything about it.
5. I've had delightful experiences with kids in F and in Envoy Class once on US, no problems whatsoever.
6. I've had my own small kids on airplanes and they were a handful although we did our very best.
So I guess I think the rule of courtesy, civility etc. should apply in F and kids are part of the world so they are occasionally to be found in F and that is fine with me!!
