| We live in China and because a lot of things have happened this year, we have now flown back to Europe 3 times after LO was born. We've done so at 4, 7 and 9 months.
Every time he has surprised me how quickly he gets over the time difference --- much faster than the grown-ups!! Every time withing 2 days he has been perfectly in the local schedule. My guess is that you will be surpised how easily it will happen.
I think the key is just to switch the meals and naps and sleep over to the local schedule as much as possible, and keeping the baby exposed to daylight when it's time to stay up. So when we fly to to Europe, I tend to add one more meal in the evening and try to keep him up as long as possible. Then let him get up in the morning when he feels like it. Then again just do meals at local hours and usually by the second evening he is already going to bed at a normal time.
As far as being in the plane, I have to say that of all our flights the ones at 4 months were defo the easiest, as LO was quite happy to just lie and play in the baby cot they give you on the plane. Now he wants to move all the time so I just have to walk him around and play with him. Luckily he's a happy little thing and loves new places and people. So I just take a bunch of toys, let him read the magazines and the safety instructions (he loves those!!), and if the people sitting nearby are baby-friendly, he loves to play with everyone around. And then nap in the cot. For the take-off and landing I always have a bottle of water for him, so he can keep taking sips to avoid the pressure hurting his ears.
Hope it all works out fine, have a great trip!! |
