So today I am flying with my 9 day old. I will update you on how it all goes. We didn't purchase a seat for her. We are gate checking the car seat and they will keep it up front on the plane. I will just be holding her during our flight. Any advice?

Edit: We made it to Florida! She did so good on her flights. We had a layover in ATL and she was fabulous. She slept most of the ride and only nursed when we came down. She was perfect during takeoff. She is going to be my little traveler.
