Paternity Leave F-Up

HR at my husband's work conveniently forgot to mention that he could take 3 months off for paternity leave instead of 2 months if I had a C-section. Our baby is now almost 1. He happened to overhear one of his coworkers being informed by HR about their paternity leave policy and he is livid. I am livid. I'm sitting at work trying not to cry because a whole month of bonding, a month of memories that can never be made, was stolen from my husband. I just needed to post this somewhere so I don't scream at my desk.
