The term "baby blues" refers to a mild and temporary emotional state that many new mothers experience in the days following childbirth. It is characterized by feelings of sadness, anxiety or irritability, often accompanied by physical symptoms such as fatigue, breast tenderness, and difficulty sleeping. These symptoms are believed to be caused by hormonal changes that occur after giving birth, and typically resolve within a few days to weeks with proper rest, support from loved ones, and self-care. While baby blues is common and generally considered normal, it's important for new mothers to seek professional help if they experience more severe or prolonged symptoms of depression, as these may require medical attention.
