So I was in an accident a few weeks ago. The other part accepted liability and the bodywork on my car was repaired. We have 3 car seats in the back, and told our insure that we would like them replaced (as per safety recommendations). They've told us to buy all new, like for like, and send them the invoice, and they will remburse us.
One of the car seats is the first stage rear facing type, which DC3 is about to outgrow, he needs the next stage up.
Would it be unreasonable of me to buy the
next stage car seat instead, and bill the insurance company?
