Thats cute, we been using my grandaughters outgrown babyseat for the past 8 yrs , our girls love it. OF COURSE, WE ALWAYS KEEP THE CARSEAT IN THE BACK SEAT for safety. We have mirrors on the front visors that we put down to keep an eye on them at all times, they love to ride !!
Good luck with your new carseat, it looks perfect for 2 !!
