It is totally normal if you and your partner are fighting more after having a baby and in fact research shows that 70% of couples experience more conflict and less marital satisfaction in the first three years after having a baby regardless of how well they were doing before children, which shows that for many couples it is situational rather than personal. And there is a lot going on. There are hormonal changes and sleep deprivation that affect mood and sex drive. There are more tasks that need to be negotiated and figured out, more financial strain and less time for each other. So once you know that we are all in the same boat and what you are up against, let go of the idea that there is something wrong with your relationship and get down to business of getting proactive figuring out how you are going to create more time to talk to each other every day, date nights and conversations about division of labor. You have to be proactive now.
