What bothers me more about "expiry" of car seats is that this logic isn't applied to other toys.

My parents gave me some Duplos from the 80s. After looking it up, the red and yellow bricks contained unsafe levels of cadmium. Legos are often advertised as being lifetime toys that can be passed down but this just isn't true.

I'd like to see mandatory UPC codes etched into toys/car seats/strollers so that they can be identified for recalls. That way this nonsense about 'expiry' of otherwise durable goods can stop while overall safety improves.
