The birth of John Hyman's first child didn't fill him with the joy he might have hoped for. Far from treasuring every minute with his son, the Rockville, Md., college writing instructor reacted by teaching more courses just to get himself out of the house. "I didn't know what my role was there," recalls Hyman, 52. His wife, by contrast, bonded instantly with their son, Jake, now a teenager. "Betsy fell in love. It was primal," he says. "I didn't have that experience. I thought I was broken."
