You should also give some consideration to safety, as well. You wouldn't take your four month old child in a car without a car seat; at least consider it for the plane. While there are very few aircraft accidents with injuries, car seats also protect against injuries from severe turbulence. Yes, an extra seat may cost several hundred dollars. But in the unfortunate circumstance that your child were to be injured on a flight, you would kick yourself for not spending the extra money.
Just something to think about....
