DS and I were rear-ended a few hours ago. Luckily he was RFing. There isn't that much damage on my car but my back is hurting a bit. My son was in his graco smart seat but I also had a kiddy world plus in my car that wasn't installed. I was actually on my way to send it back to Amazon. Im planning on getting a new car seat to replace my graco one but is it ok to still return the KWP to Amazon? Do they sell seats that have been returned? Also for those that have been in car accidents did your insurance company replace them? if so do they give you a check or a new car seat? Sorry for all the questions.
