I got our car seat inspected today (DS just graduated to convertible car seat!) by state-certified technicians. Turns out I was one of the 83% of people who had not properly installed the car seat (it was too loose.) Anyway ... the technicians said that I should take down the mirror on the rear seat headrest that allows me to see DS, who's still rear-facing. The mirror could become a projectile in a crash and even though it's not real glass, it could break and have sharp edges. I drove home with no mirror back there, but it was really disconcerting to not be able to see DS. What are folks' thoughts about this?
