(((((Ali))))) Getting the due date from a scan is just a statistical exercise. Since you know, I would say that the date of the scan being just four days different supports what you knew anyway. Beside, no one tells the little ones the due date, anyway!
We went transatlantic with our youngest at about 3 months. A bit of a challenge, but not that bad. I maintain that the sooner you start traveling, going out, things like that, the more they adapt, and it just gets easier. Which isn't to say there isn't a nightmare now and then! But little ones are creatures of habit, and habit can include dealing with different situations regularly, rather than just now and then.
