We've flown a number of times with our kids, from 3 months on up, and they've always been great travelers. One thing I learned from a family of five while we were still childless: plan to not do anything for yourself. They had all of their carryons packed for their kids, snacks for kids, and so forth, and they didn't at all sit and read or snooze; they interacted with their kids constantly. My kids (my 4 yo in particular) just loves watching out the window. He likes to watch them load luggage, watch the takeoff, look at clouds, and talk to various people on the plane. For a baby, a periodic walk up and down the aisle is nice as a preventive measure. When we were routinely flying Seattle/Mps, we would make the east bound flight a redeye to get our kids to sleep all night. We were tired, but we had family here (we were living in Seattle) who would take the kids while we caught up on sleep a little. My kids were also good at staying awake for the time in the terminal in order to fall asleep on the plane, and that was nice, too--they loved the stimulation and excitement of all that was going on. Good luck--it's crazy, but we actually really like traveling as a family!
