RE: Britax Roundabout or Marathon for
We also bought one of each (Colin is almost 4 months old, about 15 pounds and about 27" tall). We plan to have a second baby around the time Colin is outgrowing the Roundabout, so we'll just move #2 into it. And, as someone else mentioned, I wanted to leave room for a more amazing seat in a few years!
Another reason we bought one of each was for travel - I didn't want the Marathon to be my only option on an airplane. I've heard that it fits, but the Roundabout is a bit less to haul through the airport.
