More Medical Insurance Rant: How old is my child?

My insurance company, Harvard Pilgrim Healthcare,  sent the card (below) to me in the mail just in time for my daughter's birthday a few weeks ago.  The Card congratulates me on my kid's first birthday and reminds me to stay up-to-date on innoculations.  The only problem is that my kid is 12 years old, not one.  Doesn't instill much confidence, does it?
