Sorry to hear that you feel that way.
Shortly after that baby girl is born, her mother will, most likely, need to sleep (my wife did anyway.) While mama is sleeping, hold your daughter, watch her, listen to her, talk to her. The emotions that you will experience will be diverse and staggering. Pride, humility, anticipation, fear, and love are a few. I'd be willing to wager that indifference and unexcitement will not.
Best wishes to you and your family.
