I'm starting to look at infant car seats. I had assumed the car seat would go in the center of the backseat since that seems safest in the event of side impact. However, I now realized that most (or all) cars don't have the LATCH thingys in the center seat. So what do you all do? Do you put the car seats in the side seat to use the LATCH, or do you install it in the middle with a seat belt? Or is there another option I just don't yet know about?
