This is a late reply so maybe it can help someone else, not the original poster. We have a 2003 FX35 and 3 kids. We were able to fit the infant seat in the middle (a PP Viaggio SIP) and 2 boosters seats on either side (Britax Starriser Comfy and Fisher Price Safe Voyage. It was quite a tight fit though and it was hard to reach back and get the boosters buckled in. It did work though.

	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.
