Ha! Funny about the ice, that was our savior too- DD was about 1 though. I flew once with DD on my lap and once with her own seat- I do not advise going alone with her in her own seat because it is impossible to deal with a car seat on you own, IMO. I think we kept DD in her ergo for takeoff and landing?? It wasn't bad- lots for her to look at, poke at, etc. our plane had no changing table, so, yea, hopefully you won't have to, or do it ?on your seat with a changing pad... And just think, even if she cries will it be the worst 3 hrs of your life? No. Have faith. It's not as bad as you think, probably.
