Getting a passport for your LO is not a big issue. I know its not the same but i went to bali when i was 8wks pregnant and 6 kids, then again when that baby was 5mths old and 6 kids and again when baby was 11mths and 6 kids, yes the time zone didnt change and the flight was relatively short, but im just saying it is achievable, really its up to you.
