Across many households, the arrival of a child marks a profound emotional shift. Couples often describe feeling closer as a family while noticing quieter changes in their relationship. A major cross-cultural study has now provided evidence for this pattern, showing that parents tend to report lower intimacy and passion compared with people without children, even though commitment remains stable. The findings, published in the journal Human Nature, shed new light on how parenthood affects romantic love and may help explain why many couples feel strain during the early years of raising children.
The study analysed data from more than three thousand married or engaged adults across twenty five countries, offering one of the most detailed global examinations of romantic love to date. It used the Triangular Theory of Love, which measures intimacy, passion, and commitment, to explore how these elements vary between parents and non parents. According to the dataset presented in the research, parents consistently scored lower on intimacy and passion, while commitment showed no meaningful difference. The authors report that having children, rather than the number of children, was linked to these changes .
The study’s results suggest that the transition to parenthood may have a stronger effect on romantic love than family size. Figures in the report show that scores for love and its components did not continue to decline as the number of children increased. Instead, the key distinction was between those who had children and those who did not. This pattern was consistent across many cultural contexts, from Europe to Asia and Africa, with only small variations across countries.
Researchers propose that the daily pressures associated with raising children may help explain these findings. The paper notes that increased stress, fatigue, financial pressure, and work life conflict are common experiences for new parents, and these demands can reduce the time and emotional energy available for partners. Several sections of the study highlight how these challenges may weaken closeness and reduce opportunities for shared moments, which are central to intimacy. Similar patterns were observed for passion, which relies on time, privacy, and physical energy that may be in shorter supply during the parenting years.
Although intimacy and passion declined, commitment showed no measurable change. The authors suggest that couples may retain a strong sense of long term responsibility to each other, even during challenging periods. Data across the report indicate that commitment remains a stable part of romantic love, regardless of whether someone has children. This stability may help couples stay together even during periods of reduced closeness.
The research involved participants aged eighteen to ninety nine and included both men and women. Results showed some age related patterns, with older adults tending to report slightly lower love scores overall. However, the effect of parenthood remained clear even after controlling for age. The authors also found that men scored slightly higher in passion and commitment than women, although intimacy was similar across genders. These differences, however, did not change the core finding that parenthood was associated with lower intimacy and passion.
The study raises important questions about how couples can maintain emotional connection during the early years of raising children. While the transition to parenthood brings rewards, it also places new demands on relationships. The findings highlight the need for greater support for couples, especially during the first years after a child is born. Simple interventions that help parents protect time for each other, maintain communication, and share responsibilities may help strengthen relationships during this period.
