We are about to go on a 5 hr flight with our 10.5 mo old. I have not purchased a seat for her because I didn't want to spend the money. Now that it's getting closer and I see that she's moving around a lot more I'm wondering if I should get her a seat. She's not quite crawling yet but has gotten very squirmy. Also, does anyone have a list of things to bring on the plane for a baby that age? What's the best baby carrier for wearing through the airport/ on the plane for that age? If I do get her a seat, we have a Graco Snugride 35. Is it better to bring the base on the plane or go without? How do you install in the airplane seat? I was planning to bring our City Versa stroller which her car seat doesn't connect to. Do you think that will be an issue for getting around the airport with all of the gear? Any other tips for traveling with a baby? Thanks!
