So you got to the airport... Always tell TSA if you are traveling by yourself. 9 times out of 10, an agent will help you fold down your stroller or take it through. The first time I traveled by myself with C they were angels and I about cried because they were so nice. Have your milk frozen so they don't have to test it. Even if you do have liquid milk/formula, they will do a quick test. The test was usually faster than getting the stroller checked.
A neighbor flew for the first time with her young kids, and it made me realize just how unique it is that our daughter has been flying almost since birth. Our first trip from Seattle to the Midwest was when she was three weeks old for my brother's wedding. I flew home often during my maternity leave for other events, and now it is even easier with a direct flight from Charlotte. Here are a few of my favorite tips of traveling with an infant.
