Depression can affect your sexual desire. Seek professional help if the normal postpartum blues are prolonged. These roles are no longer clear-cut for many families, which can result in conflict and stress for everyone involved unless the problem is resolved. Most families need to spend time discussing each member's role, making sure that everyone is comfortable with the situation. You should also recognize that this discussion has to continue, since your roles will shift as the demands of being a parent change.
New fathers come under stress in a number of ways.
Many men feel a heavy burden of responsibility, and feel that they must now succeed financially. They often spend more time with work, just at the time when the woman wants them to spend extra time at home helping with the baby and providing some adult companionship. A new father also often feels cut out as his spouse's attention shifts to the new baby. Schedule a regular lunch or breakfast date with your wife when you can drop the baby off with a friend, grandparents, or a sitter. Many men panic about finances when a baby is born and begin to work longer and harder at their jobs.
