Is your 2 year old rear or forward facing? You could buy one Radian they have more shoulder room then they look. Do you already have an infant seat? Maybe it would fit in between one of the Graco My Rides and a Radian. At least you have time to see what will fit. But you are right even if you do have to buy 2 Radians that would still be cheaper then buying a new car.
Thanks Dawn, that's what I was thinking.
I drive an 2002 altima I can do 3 across, it's not the easiest but I have done it with a
graco cargo in the center
I have an evenflo baby seat that I hate!
