This isn't about car seats, it's about baby carriers, and it's not about protecting you in a car crash:

> When our babies were little, carriers were massively helpful in flying. The baby likes it, and your arms are free.

> The carrier means the baby can sleep wherever we are, and I can have my hands free. If you can breastfeed in the carrier, even better because the baby can eat as you’re navigating the airport, etc. Carrying the baby centered on your body is easier on your back than carrying them in the carseat. Plus it’s good for walking / sightseeing at your destination.
