Not really a health topic- can someone please educate me on car seats and car wrecks? My fiancé was in a minor fender bender last night that gave us some rear end damage. I had my daughters high back booster and my sons base/stroller in the car. Do I need to replace all of the belongings or is it just the booster I need to replace? My fiancé was NOT at fault, the lady who hit him was NOT paying attention to her driving and smashed in to our car which in turn made him hit the car in front of him!
