This may be a dumb question
All the infant car seats have extra bases available so that you can use the same seat easily in multiple cars. Just doing a quick search, it doesn't look like the same is true for convertible car seats. Am I not looking in the right place? Do you have to buy a separate seat for each car when using a convertible? (We're looking at the Britax Roundabout specifically)

Well crap.
It seems pretty impractical to only have one designated kid toting car, so I guess it's 2 car seats for us.

Is that difficult to do?

I think they're much easier to move from car to car though. So you could just take the whole thing out and put it in the other car.
No, not once you get the hang of installing car seats in general. We move my niece's car seat from my car to my mother's car every week (I watch her during the week) and it only takes a few minutes.?

Are you starting out with the convertible seat? And if so, will your LO be in daycare with one parent doing drop off and the other doing pick up?
If so, I would really want to get 2. Having to move it after every single drop off/pick up would be a PITA, but moving it every once in a while is no big deal.
Also, the daycare may not have space for you to leave the seat there during the day. KWIM??

How would you safely install an infant seat without a base?
Using the seat belt. There are instructions for both seat belt use and LATCH/base use for both Graco and Chicco.
We'll be using the base for sure, though. Seems safer/more secure and much much easier.?

ah! I always wondered what that meant, never put two and two together.:)
We will start with an infant seat, but yes it is likely that some days a different person will drop off than pick up
But DH and I work together. We could swap in the parking lot at work if need be

Good to know! We probably won't need to use a car seat in DH's car much so I didn't want to buy an extra base for very little use. Now I now, in a pinch we can still safely make it work!
Britax is very easy to install/uninstall! That said, I think it's still much easier to just have 2 (if you're going to be using both cars often, otherwise, 1 should be fine). I've heard from friends that other brands are very difficult/time consuming to install. I had a friend install hers in my car and it took her 30 minutes! She's done it a few times before too, I think it was a Graco. We have a Britax Marathon and a Roundabout and both I can install in less then 5 minutes.

I have a Roundabout (love it) and it's very easy to move between cars.
Ditto this. In the recent Chicago Tribune study, flying off the base was the most common reason for infant seat failure. That being said, the Chicco Keyfit stayed on its base, which is why we're going with this one.
