You are a brave woman! I have had numerous long flights with my little one (he is just over 2 years and the poor child has been on 11 flights in his short life!) and some of this is probably common sense, but it doesn't hurt to keep it in mind... 1. You didn't mention it, but if you can afford it, buy him his own seat. Of course under two years old, he can sit on your lap, but if he had his own seat, that can only improve the situation. 2. If he has a pacifier or bottle or special toy or anything at all that you normally don't let him have full time, bring it out in an emergency and let him take full advantage of it. 3. Check as much luggage as you can so the only things you are bringing on board are items to keep you both entertained for that long of a trip. Pack coloring books, reading books, small board games, DVD player (if you let him watch any shows), NEW toys or books. 4. Bring lots of snacks. 5. It's a simple fact that more then likely, he will break down at some point on the trip and get incredibly restless. If you are like me, we tend to worry about keeping our little ones quiet for the sake of everyone else around us. For this long of a flight, just do your best and remember you will never see any of those people that shoot dirty glances at you ever again! 6. This may already be out of your control, but schedule the flight late at night so he'll sleep a majority of the time. Or next best case - around his nap so he'll sleep a bit. 7. Finally, if you are able to pick your own seat (which I doubt on an overseas flight) select a seat towards the front - sound waves of him laughing or screaming will affect the people in front of you the most so the further up you are in the plane, they less people will hear you. Also, and I don't know your airline, but before you board, ask if there are any open seats and beg for them to place you in a row without anyone. They CAN do this and may be willing to help. Good luck and have fun!
