Unfortunately, firstborns are at greater risk for high blood pressure due to pressure and fear of failure. They experience increased stress which causes high blood pressure and can in turn put them at risk of cardiovascular disease in later years.

Therefore, when essential nutrients are not provided, it negatively affects the development of the fetus. Middle children tend to be more peacemakers.
