Thanks for all your good ideas. We will be bringing the carseat, and have bought him his own seat, so hopefully the familiarity of the carseat will help. I'm sure I'm just worrying for nothing. Its good to hear that others have survived the flight! Some of you expressed concerns about flying with 2/3 year olds. My others kids have flown at that age and it was a piece of cake. For my daughter, we bought her a sticker book that kept her pretty busy. We fly jetblue, so they had some shows to watch, but most of the time they were interested in the in-flight flight display, letting them know where we were, how high up, etc. For my 14 month old, I will definitely get the board books, and food! I talked to the pediatrician and he suggested benadryl or decongestant for the ears, which I will probably do, too.
