I too the plunge and purchased the Britax Boulevard this past weekend. My husband installed the seat, but I have a question. Are we supposed to install the seat in the middle of the back seat or behind the passenger seat? When my dd was in her infant seat we had the seat installed in the middle, now with the bigger seat I'm not sure where it should go. I currently have it rear facing behind the passenger, but I'm not sure if that the safetest place. Help!
