I don't see the problem with giving PAX who will pay a seat in a quiet area of the aircraft - i.e. no screaming kids!
It's a long flight to Florida and there are too many thoughless parents who decide to give little Johnny his first experience of flying on long-haul.
When our daughter was young we deliberately gave her her first trip to Ibiza, just a couple of hours, so it wasn't too stressfull either for her or the people around us. She was no trouble and now flies hapilly anywhere and everywhere.
