The man in the mirror

Today I took my car in for service and was given a loaner car to use. I installed Z's car seat in the loaner, but I didn't move the Bear View Mirror (we have the monkey version). I didn't realize how accustomed I am to watching Z through the mirror until my heart stopped not once, not twice, but three times in a 20 minute period when I glanced up at my rear view mirror and thought, "My baby's gone!"
