Can I use the BABY B'AIR® flight vest for children under 2 who sit on a seat independently and not on an adult's lap?

The FAA prohibits children under 2 from sitting in a seat alone without a car seat or the C.A.R.E.S. system. C.A.R.E.S. is for kids who are at least 1 year old, you can find more info about it at kidsflysafe.com. We have no relationship with the company that makes C.A.R.E.S.
