We are looking to get a newer used minivan, as our "just one more" pregnancy turned out to be twins, due in June! My older daughters will be 6 and 8 (transitioning to HBB and backless booster). The good news is we know what we need: 2 infant seats (Chicco keyfit 30) and next year 2 RF seats in the second row. What are the best options for allowing easy third row access with both infant seat bases and RF seats installed? We will be RF for 3 years, and I don't want my oldest to hate me by the end! Ideally, I would want an 8th seat and be able to install infant seats in center and drivers side second row, but it seems most second row center seats may be too narrow for this. TIA!
