Sinistar,
This is some fantastic advice as well. I will have to show my son how to adjust volume etc for his headset.. Might do the earmuff thing with earbuds so he can use his leappad while in flight
It is so weird with kids an flying. Sometimes they are so into it they forget everything else. Sometimes it isn't their thing and it takes a lot to figure out what will help.
Regarding tech to keep them busy: We carry a small portable wifi point in the plane with movies...but then kids just sit with their heads down and can/will eventually get motion sickness. Plus they are often in the back, a bit lower, can't see the ground and away from the CG.
Another big issue is fresh air: If it is stale and warm they will get unhappy and motion sick faster.
Here is our list of what we do for kids flying for extended periods of time:
1.) Let them unplug the headset's audio-in to not have to listen to all the chatter. ATIS, AWOS, HIWASS and really busy freq's can really overload them and make them nervous. Then add in mom and dad talking about where to land for an emergency, etc and they can get really anxious.
2.) Have them chew gum they picked out
3.) Make them sip some water and nibble on a few simple crackers.
4.) Show them the throw-up bag (at home), ensure them its in the plane and then downplay from there.
5.) We bring the small blue pee-bags that dry up. My daughter tried one at home, laughed and said it was easy. Greatly reduced her fear of having to potty on a longer trip.
6.) Bring a cheapo handheld fan (quite small) with rechargeable battery.....they love this...wind blowing on the face!!! I use the old iPad suction cup and mount it on side window or just hold it.
7.) We gave up on longer rides up front, the panel is so high on the 182 they prefer the back and watching a movie or something.
8.) Tablets and movies are awesome......
9.) ...but make them look out the window and spot things too.
10.) Tell them to close eyes and go to sleep.
11.) If they are young, bring a little pillow or stuffed animal they use when sleeping.
Several of those things are great for all types of passengers. Heck, my first CFI used that fan on the really hot summer days. He wasn't complaining!! I think it was like $20 or maybe even less and it will go for a few hours.
Good luck! Flying as a family to a destination, especially with an overnight,is like the best thing ever
