Car seats weren't used when I was younger we just milled around on the backseat and were sometimes told to wear a seatbelt - sometimes not. No harm came to me.
However I couldn't go out in the car without putting my DD and DS firmly into their carseats as if we did have an accident and they were hurt I would never forgive myself. My family dont seem to understand this and often tell me how silly it is that children are made to sit in carseats 
Is it just me or do the majority of you agree its unreasonable NOT to try and make your child as safe as possible? Ive tried to find some info on reduction of injury and fatality now that carseats are law but not found much. Surely its common sense though?
My husband works at a petrol station and tells me he sees many cars pull in with lots of "free" children inside. My neighbour regularly takes her 3 year old out without his. Though I know they have a seat.
Am I being unreasonable to think this is mad?
