Research Indicates Paid Family Leave Benefits Mothers and Infants

A recent study highlights the significant advantages of universal paid family leave for mothers and their infants. Conducted by NYU Steinhardt Assistant Professor Jenna Reyes, the research demonstrates that infants whose mothers had access to three months of paid leave exhibited more intricate brain wave patterns.

Last fall, the Democratic Party aimed to establish a national paid leave initiative through the Build Back Better Act, which sought to provide paid family and sick leave for all Americans. However, the bill ultimately failed to pass in the Senate, leaving the United States among just six countries globally without guaranteed paid leave for new mothers. This absence of policy places many working moms in challenging situations, particularly those lacking the financial flexibility to take unpaid time off to nurture their newborns during these crucial developmental months.

Reyes’s study, recently published in the peer-reviewed journal Child Development, found that infants displaying increased activity of higher-frequency brain waves were 7.39 times more likely to have mothers who received paid leave. The researchers analyzed a diverse range of EEG readings from infants in New York City over three months, while also collecting data on parental stress levels related to work and leave situations. Furthermore, hair samples were tested for cortisol, a stress hormone. The findings revealed a correlation between lower stress levels associated with paid leave and “distinct EEG profiles, possibly indicating more advanced brain activity.”

“The initial months of life are critical for brain development as neural connections in the infant brain flourish through warm, responsive interactions between parent and child,” Reyes stated in an interview. Importantly, the research emphasizes the detrimental effects of parental stress on an infant’s brain development, often stemming from financial insecurity.

Currently, only 23% of employed individuals in the U.S. have access to paid parental leave through their employers, with vulnerable populations facing the greatest disadvantages, including Black mothers and single parents. Reyes noted, “Many parents lacking access to paid leave return to work too soon after childbirth—one report estimated nearly a quarter of mothers without paid leave returned to work within 10 days of giving birth.”

Moreover, Reyes argues that paid leave should extend to all caregivers, including fathers. This perspective underscores the importance of reducing stress for caregivers to foster an environment conducive to healthy brain development in infants. “Paternity leave has been shown to enhance family relationships, allowing fathers to better understand their infants’ and partners’ needs,” she added.

Summary

A study reveals that universal paid family leave significantly benefits mothers and infants by promoting healthier brain development in infants. With only a small percentage of U.S. workers having access to paid leave, the lack of such policies disproportionately impacts vulnerable populations. Expanding paid leave to all caregivers could enhance family dynamics and child development.
