It's long flight, kids or no kids! Just know it will be over soon and you will be home and all will be fine! Be prepared for when you home for them to be off as well !! After only sleeping one hour on the flight home, we went to bed about 1 am and dd was up at 5 am!! ARGH! Also, make or buy some frozen meals for the first week or two home! You will be glad you did!
Lots of snacks, lots of small toys (I got a lot form the dollar store). Make sure you don't get things that can roll, toys WILL get flung! I made dd sleep the one hour she did by holding her while she cried until she finally fell asleep. At least three or four changes of clothes, while we didn't have any diaper problems, she did make food messes on her shirts. While the flight was long, dd wasn't bad at all, she was 18 months and it took a lot to keep her busy and entertained and fed and she didn't sleep!
If you can get the bulkhead, it's so nice! We got her a seat so she was between me and my mom and the extra room even for playing was great, but she wanted to spend most of her time on the floor. Bring a blanket or something they can sit on!
Mostly, enjoy! You are bringing your child home! Here's Delaney doing some duty free shopping! It's funny, she slept most of the four hour flight from Siberia to Moscow. Go figure! (oh, also, at 18 months, she was not interested in watching a DVD, I do not think she had ever seen TV!)
