I know infant car seats expire 5 years after their manufacturer date, but does the same go for extra bases as well? I have two Graco Snugride 22s I am planning on using for *my twin dds due in early June that each came with a base, but now I need to find two more extra bases, and really was hoping not to have to buy brand new ones. *I have a friend who I know well that has a base that is still in good condition and never been in an accident, but the manufacturer date was 070506. *Also I have a second friend same conditions that has one that was manufactured 012208. *So my question is can I or can't I still use these bases? *Thanks in advance for your help.
