IamA Car Seat Safety Expert AMA!
I'm a husband, father, and have dedicated the last decade to becoming an expert and advocate on car seat safety and best practices on car seat use (e.g., extended rear-facing or extended harnessing), as well as on factors related to auto safety for drivers, cyclists, and pedestrians.
On my site, The Car Crash Detective, I work to review every car seat on the market (and have purchased, borrowed, or sold more than 200 at this point) and provide a resource for parents through a range of articles on what to and what not to do when it comes to keeping kids safe in vehicles. Ask me anything related to keeping kids safe in cars or car safety in general and I'll do my best to answer.
Edit: It looks like everyone has gone to bed! Thank you all for the questions, and please feel free to post more if you have more. I'll be back in the morning to check : D
Edit 2: It's 7:35 AM Central and I'm here for another hour or so to field more questions.
Edit 3: Lots of questions! I'll stick around for the rest of the day checking and answering. I hope this has been helpful for everyone.
