"I’m not big into going to the doctor. It took most of the humility I had to turn to the Google bar and type in “postpartum depression” and “men.” I was surprised to learn that as many as one in every four new dads suffers from some form of the doldrums. That’s 2,700 new fathers each day, nationwide. I found out that after childbirth, a man’s testosterone levels ebb while his estrogen surges—conceivably to make him a more faithful and nurturing parent; no one’s sure. The hormonal shift leaves us just as susceptible to mood swings as Mom. And it’s thought that a major trigger for depression is the lack of response from the child."
