Women and babies are the stars of childbirth, but dads play an important role, too. From massaging an exhausted mother-to-be's back, to reminding her of her strength when she is at her most vulnerable, a supportive partner can make an enormous difference in labor and delivery.
So in honor of Father's Day, we asked the International Association of Professional Birth Photographers for photos that capture the important emotional and physical support dads-to-be provide their partners, as well as the utter magic of fathers meeting their babies for the first time. Here are 35 of them, with captions from the photographers.
(Note: Since the photographs below depict women in various stages of childbirth, some may not be suitable for viewing in all situations.)
