A few years ago, something like 17. We bought a car and installed a rear facing car seat. This was a Volvo station wagon, and Volvo is probably the only car company who still makes these rear facing car seats.
Once we got the car seat installed, we took a picture of the three kids we had at the time. When I recently bought a “new to me” car and it had the same rear seat in it, I could not resist getting that same picture again with the same three kids.
