I'm a FTM so forgive me if this should just be common knowledge but my husband and I were talking about where in the backseat the car seat should be placed and I wasn't 100 percent sure. Should it go in the center of the back seat or behind the driver side?

Re: Carseat Placement
Definitely check the carseat manual, and your car's manual as well.
You should also consider who's sitting in the front. In my car, the car seat worked better in the middle, as it gave my husband more room to sit in the passenger side... and in his car, the seat would only fit in the passenger side.

Unless your car manual says differently, the center in safest followed by the passenger side and then the driver's side.
My car manual says the sides are safest because the middle seat is too small. If you have a sedan, make sure to double check.
Agree. However, if you have two they both can't go in the middle lol. So I say figure out what works in your car. We have to put the car seats on the sides (behind passenger side and driver's side) because the middle section of our car doesn't allow the attachment. We've tried a million different ways and taken them to the fire station. That's the only way that will work.
As with all other safety things do your best and drive carefully.

That is usually NOT allowed, unless your car manual or carseat manual says otherwise.
My understanding is to place it in the middle of the second row if possible, further from a side impact on either side.
Once you get to #2 if you can't fit two car seats next to each other, or don't have a bench seat back there, it is better to put the new born behind the passenger seat.
We always do that because it is safer to load from the curb side anyway and the older child can crawl across to his seat anyway (And then I reach across from the curb side to fasten the seat belt.) I would not be comfortable carrying an infant seat around to the street side and loading from the street. I guess to some degree this depends upon where you live, maybe it's not an issue in suburbia?
This. My sister is a CPST and helped us practice with our seat last week. She said the preferred order is middle, behind passenger, behind driver. Basically, put the most vulnerable person (child) in the center of the back seat, then work to the sides.
She just had her 2nd child in late April, her 3yo is in the center, forward facing in a 5point harness, her 5 week old is behind the passenger. She said an infant seat provides more encompassing protection than the FF convertible seat, so baby is on the side and toddler is in the middle. FWIW she uses a Chicco Keyfit for the infant, and a Diono Radian convertible seat for the toddler.
FYI most vehicles do NOT have center LATCH, and using one latch from the two side seats is NOT recommended, depending on whether your infant seat uses rigid LATCH or flexible LATCH. We have a Mercury Mariner, which is Ford, and will be using the center seat seatbelt to install our infant seat.
To find the nearest location to have your seat inspected, go to seat check dot org. Many fire and police stations can provide a check, but some can or will not, it is not a universal thing.
