We've got a
Chicco Keyfit 30 in "Race" colors for our son.
Note: This seat, like all modern infant seats, is HUGE! In order to fit it in the car (behind the passenger's seat), the passenger's seat must be all the way down and a lot of the way forward... and then, I can just BARELY fit in that seat... it's more comfortable to sit in back next to the baby.
He's getting too long for this seat (30" max), so we're in the process of transitioning to a
Graco ComfortSport convertible car seat, which also just BARELY fits. If anyone knows of a better option for a rear-facing seat, I'd love to hear it!
