[third on the way]

We have the 2006 RX400h and love it. Today, we just bought the Radian for our 4 y/o and will be using the Roundabout for our 2y/o and the PegPrego infant seat for baby #3 on the way. All 3 seats fit nicely.

We are trying to look for another car with an accessable 3rd row (for extra passengers), but want to put all 3 carseats in the second row. Cost is not an issue, but gas mileage is. Do you have any suggestions?

	Infant Car Seats Infant-only rear-facing seats are for babies up to about 22 to 30 pounds, depending on the specific car seat. You will need a new seat when your child gets bigger. Infant-only seats have handles that allow you to move the seat from the car to the house or other locations. Some have a base that you can leave installed in the car, so you can just click the car seat into place each time you use it.

	Britax Roundabout - Click for more info With the introduction of the new LATCH laws, Britax has improved even further upon their famously popular Roundabout Convertible Car Seat. This car seat has been praised by just about every consumer safety organization and mom and dad out there - and for good reason. It is easy to install, compatible in just about every car, super comfortable for baby, stylish and most importantly safe! Ask around and you will see that everyone raves about this car seat.

	Sunshine Kids Radian 80 or 65 - Click for more info If "the Sunshine Kid's Radian 80 convertible car seat is (probably) the only car seat you will ever need," the "probably" part of this statement comes into play when you directly compare the Radian 80 with the Britax Regent. While the Radian 80 has a very high weight capacity, the seat width is only 10" vs. the Regent's 14" seat. The Britax Regent may be a bit wider, but it is very bulky, is only forward facing, and does not fold like the Radian 80. Because the Radian 80 is so narrow, you can potentially put three of them side by side in the back seat. Three Regents side by side? Impossible.
