Baby's always go behind the diver . They have more protection . After they turn 2 and weight a certain amount then you can turn them around and I wouldn't recommend middle unless you have 2 baby's or 3 and have no other choice

I put my baby girls in the middle..I have a 2014 Bmw though. don't kno if every car is set up that way. I know you can put the carseat in without the base because I was with my in laws over the weekend & they didn't have the latch system, so we just put the shoulder & lap belt in the slots on the side.

Depends on the car. For example my car isn't set up to have car seats in the middle seat. Look up The Car Seat Lady on Facebook. That page has a ton of info!

infants always go in the middle.

What's the latch system? The bottom part?

Good question I would like to know also

I've always heard never to put them in the middle. they can fly through the front seats. If they are on the sides they will hit the seat.

I have the latch system and mine is in the middle. It's recommended for the middle because they say it's safer in case of a wreck, less impact!
