Sus: I think tavelling for tour & travelling for stay is slightly different. Tour you want to make full use of every waking hour there... stay, you are staying for a year... can slowly adjust...
I shouldn't think that there is too much to worry about for you ba, if body jetlag, just sleep it off... only a couple of days... or at worst a week? Just make sure you have ready food available for the family should you guys wake up in the middle of the night. Cos US is unlike Sg where food is available 24/7. Or if your HB is flying there 1st to get the apartment settled, etc, then even better.
Some ways to get round it, though not always foolproof... is to align yourself to your arrival time a few days before departure & also on the flight... i.e. if you are arriving in the evening (local) time, stay awake, as much as you can on your flight. So that your body wears off & you can sleep upon arrival (which is their sleeping time). Conversely, if you are arriving in the morning, sleep as much as you can the entire flight, so that you are so fresh & awake upon arrival.
I find that the flight helps cos it's so super duper long... & you won't know night or day... cos shuttles down at times & at others, you are travelling across time zone, can feel abit luan qi ba zhao... but dun bother, just align to arrival time.
Then again, we adult can adjust, I'm not sure how to tell BB to do it.
I've not brought my younger ones across time zones, so can't tell. But I think babies are supposed to sleep/ nap anyway. Just let them lol.. maybe since you are looking after Calab youself (without help?), you might want to align to his timing instead... cos even if u r aligned to local time liao, but he's still adjusting, you still need to stay awake to care for him mah...
Just my 2 cents worth... from a combination of material I read in travel guide books on bringing kids/ babies, personal experiences & thoughts... really Nova would be a better adviser for this... *smile*
BTW, I just recall, if you are able to make a trip to the local library, do check out their guide books. There are plenty on bringing young children & babies across time zones...
My problem when I brought #1 was that, we travelled on SQ with plenty of entertainment & both father & child could stay on it the bulk of the entire flight! We were arriving in the morning, so had to keep nagging the gal to sleep lol...
No, please dun give cough mixture for nothing & without dr's advice. When #3 was down with flu, a few weeks ago, Dr did not want to give any med, other than the nose drop. Cos she mentioned that it was mild & antihistamin may cause bb to stop breathing altogether! You won't want an unnecessary emergency. Just let him b, babies are smarter than us at adapting...
