I am expecting my third child in January. This has me thinking alot these days. My carseat system (carseat, base, stroller) will be 8 years old at that time. I pulled it out of the attic yesterday and everything seems to be in working order. I installed in the the car and everything still locks down tight. Most of my friends are telling me it is still fine to use. But there is a sticker on it that it expired 2-3 years ago. How exactly does a carseat expire and should I just get a new travel system? I really liked the travel system I used it all the time with my other 2 children.
