"When a father has a chance to hold his newborn skin-to-skin on his chest he releases oxytocin, often called the love hormone. This hormone supports bonding and trust in humans, and is the same hormone that makes a woman’s uterus contract in labor. When the dad’s endocrine system releases oxytocin as a result of this skin-to-skin contact with his newborn, he can’t help but fall in love with this new little person. His body is flooded with oxytocin and the connection grows." - SheKnows
