My first baby was born in Hong Kong in June and when she was seven weeks old I travelled to England with her. I didn?t notice that she had jet lag on the trip over to England as she was still waking every three to four hours day and night at that stage. She was 12 weeks old when we returned to Hong Kong. We travelled on Gulf Air and the flight, with changes, took 23 hours with six take offs and six landings! I was advised to feed both taking off and landing so we spent most of that 23 hours feeding. Once back in Hong Kong we both slept for ages and the only thing that happened was my periods returned a couple of weeks later. (I later found out this is common when your baby goes more than six hours without a feed ? even if it is the only time she does it.) The English summer was much cooler than the Hong Kong one but she adjusted fine except for one windy walk where she cried because she was cold but I put her inside my coat and she was fine after that.
My third child was born in England and we flew to Hong Kong when he was 18 days old. I had to travel to Liverpool to get his passport as waiting for a postal application would have taken weeks longer. I remember on the flight the women in the next seat to me had a 12 day old. I remember being worried about travelling with such a young baby so I contacted Cathay Pacific to ask if they had any guidelines. I was told that a healthy full-term new-born can fly from being 24 hours but that they don?t recommend a new mother to fly for at least two weeks because of the risk of postpartum haemorrhage. I found flying with such a young baby easier than when they are older. All they do is feed and sleep ? same as if they are at home. So it really just depends on the mother's comfort at feeding and coping in public.
I have four children and have flown with babies of just about all ages. I found toddlers to be the hardest to fly with. They aren?t use to sitting still for such long periods and take-off, landing and turbulence can be trying when they need to wear their seat belts and not move around. I usually ask for a child seat belt so they can sit on my knee even if they have their own seat, as it is nice to be able have both choices open to me depending on how the child is behaving at the time. Jet lag is much more of an issue in a toddler too.
The only thing I noticed with young babies is that the time that they poo is affected by jet lag. Quite early on my babies started to poo in the daytime and not the middle of the night. But with jet lag they would poo in the middle of the night. And somehow a baby needs to be awake to poo ? which meant I was awake too.
Best wishes with your travels,
