I was wondering if anyone's had experiences flying with young kids on their lap. We're going to have to be making a cross country trip next month kind of unexpectedly, and will be bringing our 3 1/2 month old daughter. I know airlines allow you to carry a baby on your lap, which we were planning to do. In asking about flights on another parent group thing, I got feedback about how unsafe this is, and how it's much better to buy a seat for her and have her in her car seat during the flight. Now I feel a bit torn about this. Realistically, I don't know if we could afford the seat for her (tickets aren't cheap, especially so last minute-ish). And, I know it is obviously safer to have her in her seat on the plane, versus checking her seat/having her on our lap. Though, again, I don't know how feasible it would be to do this. Does anyone have any experience? Am I being a bad mom for thinking about doing what is more affordable/realistic versus the utmost safety?
