When my daughter got sick, I was on the phone to the doctor's office while my wife held her. The nurse on the phone asked for her date of birth. My mind was a complete blank -- I had to ask my wife!
Of all the titles I've held in my life, "Daddy" is the one of which I'm most proud. Of all the jobs I've held, "Worried Daddy" is by far the worst.
She will come out fine. The trick is for you to try not to tear all of your hair out waiting for it! Best wishes.
