S.A.
I flew with a 1 and 3 yr old to Austria (12 hrs) and this is what I did. They let me have sippy cups with milk going through security and any dry snack. I took crackers and candy (really small like tic tacs). I also brought a cooler empty in my carry on. Once I got through security I went to McDonalds and bought kids milks for the plane. not all planes have milk for hte kids. you can buy juice if you want. I then filled baggies with ice and placed it all in the cooler I had. This was easy so i didn't have to keep call the flight attendant to bring me juice when the kids wanted it. You can look at the airline you buy the tickets from some of them now have on demand movies and personal screens. The best toy I took were little magnadoodles I bought at teh check out lane at target. They used these forever! The kids also like to use wipes and clean the window and backs of chairs. If you havea assigned seating and not to much carry on luggage I recommend NOT pre-boarding. Keep the kids off the plane as long as possible. ALSO!! as for the first row in the class you purchase. It has more leg room and the kids won't bother anyone kicking their seats.... Beg plead and borrow to get you guys in the front.... good luck and it won't be bad...
