I have a 26 month old daughter who is still rear-facing a Marathon, and we are expecting baby number 2 in March. I just cannot decide whether I should keep one in the middle, or have it fair and even and have both outboard. And if I was to keep one in the middle, how do you choose which child? I would like to put one on each side, but then I feel like the best spot in the vehicle is being wasted...I just don't know! Any advice?
