When we just flew to the US (we got home last week) our boys surprised us and were wonderful. We had the A330 which was lovely and had our own tv's with lots of movies for us and the kids. There was even nickleodeon on there.
With Theo we just let him do what he wanted and he slept when he wanted. So he had lots of shorter naps as opposed to his 1 nap of 2 hrs. Harvey however we could not get to have a decent sleep until the last flight (3 in total) when he was so exhausted because he woke at 1am to leave for the airport and didn't sleep until almost 1am our time. He did have like 2 naps of about 20 mins but that really was all. Then his last nap was for about 1 hr, but he doesn't nap at home no longer.
They both fell straight into the timezone, but then it was night time in Utah by the time we got there.
See if you can get seats behind the Galley as they had more leg room which allowed H & T to walk around a little in front of G and I.
We took too many things to entertain them on the plane because we thought we would need them. Infact the time went pretty fast and we didn't use any of the things we took.

Also, just a nice thing is, ask the cabin crew if they do the 1st wings for your child (if its your childs first flight) as they may get a badge and certificate for a keepsake.
