My philosophy on traveling is to have a tool box. It should be full of everything and anything you could possibly need to help deal with hunger, tantrums, etc.

My toolbox has premade bottles for the boys and millions of snacks. I usually pack things like yogurt bites, crackers, baby food, and fruit. I also pack Joey's backpack full of books and toys. I bring stuffed animals and toys that do not make a lot of noise so we do not bother the other passengers. We will read Five Little Monkeys five times on a one-hour flight; Joey loves it. He is also just starting to watch videos. Joey will play on Casey's iPhone and watch Elmo or Mickey's Play House.

I also recommend having hand sanitizer. Joey touches everything so I make sure to wipe down the trays and seats as soon as we get on the plane.

Recently my nutritionist suggested an all natural supplement to give the kids to help build up their immune systems. I give the kids Congaplex a few days before we travel to help fight anything they may catch from other passengers.
