In cases of postpartum depression, women primarily exhibit emotional excitability, as well as anxiety, feelings of helplessness, guilt, and concerns about being unable to support their child. Severe cases may involve fears of the child suffering in the world, leading to infanticidal actions, and even suicide. This condition generally occurs more frequently in women who have a history of mental illness. Following childbirth, due to physical discomfort, emotional instability, and factors such as sleep disturbances, these adverse reactions are likely to be exacerbated.
