For pregnant women, the COVID‐19 pandemic has resulted in unprecedented stressors, including uncertainty regarding prenatal care and the long‐term consequences of perinatal infection. However, few studies have examined the role of this adverse event on maternal wellbeing and infant socioemotional development following the initial wave of the pandemic when less stringent public health restrictions were in place. The current study addressed these gaps in the literature by first comparing prenatal internalizing symptoms and infant temperament collected after the first wave of the pandemic to equivalent measures in a pre‐pandemic sample. Second, associations between prenatal pandemic‐related stress and infant temperament were examined. Women who were pregnant during the COVID‐19 pandemic endorsed higher pregnancy‐specific anxiety relative to the pre‐pandemic sample. They also reported greater infant negative emotionality and lower positive affectivity and regulatory capacity at 2 months postpartum. Prenatal infection stress directly predicted infant negative affect. Both prenatal infection and preparedness stress were indirectly related to infant negative emotionality through depression symptoms during pregnancy and at 2 months postpartum. These results have implications for prenatal mental health screening procedures during the pandemic and the development of early intervention programs for infants born to mothers during this adverse event.
