Maternal mental health has a profound impact on the health and wellbeing of the child. Since the onset of the pandemic, rates of postpartum depression have increased, affecting an estimated 1 in 5 women.1 Numerous studies show the impact of postpartum depression on the newborn child across multiple domains, from bonding to healthy weight gain to meeting developmental milestones.

While new medications are being studied and approved to specifically target postpartum depression, these treatments are inaccessible to many because of high costs and long wait lists. Beyond medication, structural changes such as paid parental leave have been shown to have a substantial impact on maternal mental health, thus impacting the health of children as well.
Implications for Mothers and Children
Psychiatric diagnoses such as postpartum depression are on the rise.1,2 This is likely attributable to a combination of factors, including increased isolation since the start of the pandemic, worsening health inequities across race and socioeconomic status, and difficulty accessing mental health care.3-5 The effect that postpartum depression has on the family is significant for the newborn as well as other children in the home.
Dr. Misty C. Richards
Data suggest that postpartum depression impacts both the physical and mental health of the child. Infants of mothers with postpartum depression may experience challenges with weight gain, decreased breastfeeding, sleep disruptions, and delays in achieving developmental milestones.6-9 They may also show decreased maternal infant bonding, challenges with cognitive development including language and IQ, and increased risk of behavioral disturbances.10,11 These effects are likely attributable to a combination of factors, including decreased maternal responsiveness to infant cues.7,12 Many of these effects are mediated by the chronicity and severity of depressive symptoms, suggesting the importance of screening and treatment of postpartum depression.10,11 However, treatment for postpartum depression can be difficult to access, particularly given the increased level of need.
It is therefore critical to consider what structural interventions and policy changes can decrease the risk of developing postpartum depression. Data consistently show that access to paid parental leave improves maternal mental health outcomes. Among patients with access to parental leave, research shows that paid leave of longer duration, at least 2-3 months, is the most protective.13 Studies have identified decreased depressive symptoms, decreased stress, decreased use of mental health services, and decreased hospital admissions among women with longer parental leave.13 The positive effects of paid parental leave on maternal mental health can extend beyond the postpartum period, solidifying its impact on the long-term health outcomes of both mother and child.13
Advocacy Is Imperative
In 2024, the United States is the only high-income country, and one of only seven countries in the world, that does not guarantee access to paid parental leave. The Family Medical Leave Act is a 31-year-old federal law that requires some employers to provide unpaid leave to eligible employees. It is narrow in scope, and it excludes many low-wage workers and LGBTQ+ families. Thirteen states — California, Colorado, Connecticut, Delaware, Maine, Massachusetts, Maryland, Minnesota, New Jersey, New York, Oregon, Rhode Island, and Washington — as well as the District of Columbia, have enacted their own paid leave policies. However, there are no federal laws requiring access to paid parental leave. As of 2023, fewer than 30% of workers in the United States have access to paid parental leave, and only 16% of employees in the service industry have access to paid parental leave.14 This disproportionately affects families from lower income backgrounds, and further exacerbates socioeconomic, racial, and gender inequities. From a health systems lens, this increases risk of adverse maternal mental health outcomes among those who already have decreased access to mental health services, worsening health disparities.
Paid parental leave has strong public support across party lines, with polls showing the majority of Americans support comprehensive paid family and medical leave.15 Despite this, the United States has failed to enact legislation on this issue since 1993. Multiple attempts at expanding leave have not come to fruition. In the past year, both the house and the senate have announced bipartisan efforts to expand access to paid parental leave. However, legislative frameworks are still in early stages.
As physicians, it is crucial that we advocate for expanded access to paid parental leave. We must use our expertise to speak to the impact that paid parental leave can have on the mental and physical health of parents, children, and families. By advocating for paid parental leave, we can help create a more just and equitable healthcare system.
