Car seat

So I put the car seat into my car the other day. Now I'm actually driving around with the base in the back seat ... a not-so-subtle reminder that everything will change in just a couple more weeks.

Here's the thing, though: The instructors at one of our baby classes clearly said the center of the back seat was the safest place for a baby seat. Unfortunately, we only have the LATCH hookup on the sides, not in the center. To further confuse things, the instruction booklet and info we've seen online says to always use the LATCH if it's available. LATCH, everything explains, allows the seat to be attached directly to the frame of the car, making for a far more secure hookup than a seatbelt.

So which is it? Is LATCH on the outside safer than seatbelt in the center?

And how is the thing supposed to be securely attached when it's attached at two points in the back? Won't the front move from side to side no matter what? Is that secure?

Nobody told me there'd be questions like this. We're running out of time!
