T.B.
unless you are mr. trump or won your own plane you will have these concerns. first of all, it is natuarl tobe concerned. what did with the then 11 month old man (he will be 4 in november) when we were flying from nyc to chicago was nurse him on take off and landing. it went very well. bring his favorite stuffed animals, get there early, play with him, and because you can board earlier than the rest of the passangers, you can get him confortable etc.
you'll do very well!
infact i felt so safe with him that i was not concerned about heavy wind and bumps as we got closer to nyc on the return trip. it was very windy and the guy near me was grunting about the bumps, i closed my eyes, held him close and felt so safe. they are angels....
