We are now expecting #3 (yay!), but based on some preliminary measurements, we're thinking that we may need to get TWO new cars, something we weren't planning on... So, I'm wondering if anyone has suggestions for 3 compatible seats or if anyone has done 3 across in either a 2001 VW Passat or 1998 Honda CR-V? By the time this baby shows up next April, my oldest will be 5, and #2 will be almost 3. We currently have all Britax seats: 1 Parkway, 2 Marathons and 1 Roundabout, and would obviously love to keep these seats and get a seat for the new baby that would work with them (although I can't remember the weight/height limits for the Roundabout...). Oh, and BTW, the baby's seat doesn't *have* to be an infant seat - I'm perfectly happy w/ a convertible RF seat if that works best. Suggestions?
