First Year of Marriage/First Child Born

I briefly discussed what I learned in class with my family over the weekend. My boyfriend had some interesting insights that I felt would be beneficial to share:
"One trouble that newlywed couples run into occurs at the birth of their first child. The family dynamics radically change. What was once a single bilateral relationship, becomes three independent relationships. One of the problems that occur with the development of these relationships is due to the inherently close relationship of the mother-child relationship. The husband and father can begin to view this relationship with jealousy because that relationship is often built by neglecting the two relationships that he is a part of. There are several ways to avoid marginalizing the husband in the family when the first child is born.
"Your mother (he was referring to my mother) made it sound very simple, 'You feed them, and he changes their diaper, and there you both have a relationship with the child.' While this answer is simple, it gets to a fundamentally strong suggestion, by allowing the father to help with daily regular chores with the child he can begin to develop a relationship with the child, and by giving his wife the time away from the child to recoup, she can spend additional time and is inspired to preserve her relationship with her husband."
