Congratulations to you and your wife! If you think you've ever been busy in the past, just wait!!!
I speak from experience that once they get past that backward facing car seat issue, you can put a regular one in the passenger seat--my 6 year old daughter and I often go cruising for ice cream in the summer with the Pagoda "Kiddy Car", car seat on my right, daughter safely strapped in with the 3-point retractables, and everyone is happy except the wife because there is no room for her!
