I'm new here, but I have been stalking the threads for a few days. We have a 2.5 year old daughter in a Britax Roundabout 50, and we are TTC baby #2. I currently drive a 2010 Ford Fusion, and I would like to keep my car for as long as possible. I am wondering how others have installed a Roundabout or other convertible seat and an infant carrier. I would like to be able to ride in the back with the babies if necessary. Would it be possible to install the infant base in the middle and Roundabout outboard with room for me? I have not purchased an infant seat yet, and I am not opposed to changing DD's seat if the fit will be better/safer. I would appreciate any advice or suggestions you all may have.
