Never would have thought of this...Emergency Contact information for rescue workers on both sides of every car seat. Child's name, phone number, etc. In the event of a wreck most children in car seats can't or won't be able to give this information to rescue workers.
SUCH a cute way to tell your dad he's getting a "promotion". Could also make it "The best parents get promoted to grandparents" for both mom and dad. Definitely doing this in a million years when I get pregnant with the first!
