When Does a Car Seat Expire
A car seat is one of the clearest replacement pages in the whole database. The date that matters is usually tied to the seat itself and the manufacturer instructions, not to a generic household memory of when it was bought.
Baby items are easiest to manage when the reminder is tied to the printed date, the opening date, or the exact product label you are using.
