Just got back from NZ trip with 6 month old - was nervous before we went, but it was absolutely fine. Like many of the people before have said, its a pretty perfect age for travelling - my daughter hardly even noticed we were doing something "different" - she continued to be hungry as normal, tired as normal etc... - if anything she was rather sleepier than usual - the buzz of the plane, the excitement (who knows?) - the only times she did proper crying - like the kind i was scared of, and as a passenger before babies, the kind of crying that i dreaded when seeing a little baby on board - was during landing, and that was only when i failed to get her drinking/sucking in time - pretty much as soon as they say that descent is starting (usually about 20 minutes before actual touch down) get your baby sucking (whether boob or bottle) - i had been advised that breastfeeding wasn't the best idea, so in the couple of weeks before we left i dropped down to half and half, but actually whilst flying found it useful to have both options available! The time difference was another big worry, but we just did our best to keep busy and outside during the days once we arrived, and she settled (both going there and coming back) within 2 days and was back to sleeping proper times. The whole thing was really so much easier than i thought it would be...
