"Prenatal stress refers to the physiological and psychological stress experienced by expectant mothers during pregnancy. It encompasses a wide range of stressors, both chronic and acute, that can significantly influence the intrauterine environment. These stressors may include maternal anxiety, depression, exposure to traumatic events, socioeconomic challenges, and environmental factors such as pollution and noise." (Jagtap, et al, 2023).  There has been significant research done in the field of prenatal neuroscience as experts seek to find connections between the prebirth development of a baby and how that development effects later social emotional learning. While the ramifications are widespread, there is evidence to suggest that stress prior to birth, found in the cortisol "stress hormone" that has been shown to affect babies before they are born. While many factors can add to that stress, they can all serve to create developmental hardships later in life for the yet to be born child.
