On our first trip in 2002, I thought I was prepared because I brought bubble gum for the kids to chew if their ears bothered them. Well, little did I know that DD6 did not like the flavor of gum that I brought, so she didn't want any. Takeoff was fine, but when we started to descend, her ears started hurting, so much that she started crying from the pain. A nice flight attendant came over and told her to suck on her thumb. She did, and it really helped! So, on future flights, I've always brought things to suck on - l ike those baby bottle pops or ring pops and also gum (that helps me as well). So, I would bring a variety of things to try in case they are affected by pain.
