We just bought tickets for our trip to AZ for Christmas to see the MIL. We decided to buy a seat for DS since I don't know that he'll let us hold him the whole time, do we need some form of identification for him? I filled his info online and birth date but didn't know if he needs a copy of his birth certificate or not? Also, did you bring a seat restraint along or just buckle him in the seat?
Thanks ladies

Re: Questions on flying with LO
We have never brought anything when we've flown domestically - obviously internationally you would need a passport.
Since he has his own seat I'd bring his carseat on the plane. Much more comfortable for them and easy for you to keep him somewhat contained and happy in the seat vs. being able to wiggle out of a lap belt!
We always bring a bag of snacks/sandwiches - lots of options for the kids. Also if Bex likes milk, pack an extra sippy or buy it after you get through security. A lot of times domestic flights only have one or two milks for coffee, not for actual drinking.
To keep him occupied I'd bring books, coloring books, sticker books, whatever he's into. Right now Colin loves stickers, so when we go to SD's volleyball games, I bring along sticker books and those keep him occupied the whole time! Possibly ipad/tablet loaded with some shows/movies?
Good luck! We've done it many times now and as long as your prepared it's not bad!
