So we did make to the fire the department. And, good news: They gave us the thumbs up for our infant car seat. Granted, the front passenger seat is now a bit crowded and I don’t think anyone over 5’5″ can sit comfortably there while the car seat is installed, but it fits! (And I fit, although Sofia now has to sit in the back.) The fireman was very sweet and very helpful. I felt much better after that visit. And now, in addition to our jogger, we have the snap-n-go stroller that fits our car seat. We are ready.
