We're off to Florida soon (via Toronto!) and although I've just read someone else saying that they think 2-3 years is the worst flying age, I've got a frightening feeling that it is actually at around 18 months, when they're too young to be occupied with anything for long and just want to be exploring/ climbing/ destroying. And they're too young to reason with in the slightest.
So bearing all that in mind, has anyone got any tips please?
Any help much appreciated!
