Although big changes in an expectant mum are obvious, a father also goes through a lot as he waits for the new arrival. It's a time of adjustment as he changes his self-image and his relationship with his wife and other children to make room for another. Some dads change their appearance, such as growing a beard; others take a second job to be sure they can support their growing family. Still others fix up the house or take on a new project. All will be thinking about their own fathers and wondering whether they will be the same or different. Most feel pretty anxious, though men can have a hard time showing it.
