You might be the most optimistic, affectionate pregnant couple right up until the moment your baby is born. The months after your first child’s birth, however, may be one of the most difficult periods of your or any couple’s life. Problematic communication patterns that couples that they had worked through may return, sometimes with more intensity than ever. This phenomenon is well documented in the scientific literature, and there are many films about it (Two days in New York, Knocked Up …). And yet, new parents often feel unprepared when it happens to them. These new parents are relieved to hear that it is normal to feel exhausted and disoriented in your new role as a parent. And it is also completely normal to fight more with your partner during the postpartum period.
