Maternal health involves healthcare during pregnancy, childbirth, and postpartum to reduce risks to mothers. During pregnancy, a woman's body undergoes many changes like morning sickness, breast enlargement, and uterine stretching as the fetus grows over 9 months. The placenta exchanges nutrients between the mother and fetus, so mothers must eat healthy and get medical care to support the developing baby's health. Common symptoms mothers experience include fatigue, nausea, breast changes, and skin/joint issues. Breastfeeding is the ideal way to feed infants for its nutritional and emotional benefits to both mother and baby. Responsible parenthood guided by conscience involves respecting spousal roles and transmitting life according to God's will through loving service.
