During pregnancy, a mother and baby exchange various substances primarily through the placenta. Oxygen and nutrients, such as glucose and amino acids, are transferred from the mother to the fetus, while waste products like carbon dioxide and urea are sent from the fetus to the mother for elimination. Additionally, antibodies from the mother can pass to the baby, providing immune protection. Hormones and other signaling molecules may also be exchanged, influencing fetal development.
Oxygen, nutrients (such as glucose and amino acids), antibodies, hormones, and waste products (such as carbon dioxide and urea) can be exchanged between the mother and fetus through the placenta. These substances allow for the fetus to receive essential supplies for growth and development while also enabling waste removal.
During breastfeeding, various substances transfer from the baby to the mother, primarily through skin-to-skin contact and hormonal signals. These include hormones like oxytocin, which can promote bonding and maternal behaviors, as well as immune factors that may signal the mother's immune system to produce antibodies. Additionally, pheromones from the baby can influence the mother's emotional state and behavior. This exchange enhances the mother-infant bond and supports the baby's health and development.
During pregnancy, the baby passes various substances to the mother through the placenta, including hormones and metabolites. Additionally, fetal cells can enter the mother's bloodstream, leading to microchimerism, where the mother retains some of the baby's cells. This exchange can influence the mother's immune system and overall health.
One of them is vitamins/ food which comes from the mothers food which is needed for the baby to survive.
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.
The unborn baby's circulatory system includes the umbilical vessels which connect it to the placenta to exchange substances with the mother's system. When the baby is born these vessels are disconnected.
Oxygen and nutrients, such as glucose and amino acids, pass from the mother through the placenta to the embryo. These substances are vital for the growth and development of the baby during pregnancy.

During pregnancy, the baby can transfer several substances to the mother through the placenta. These include hormones, such as human chorionic gonadotropin (hCG) and progesterone, which help maintain the pregnancy. Additionally, fetal cells can enter the mother's bloodstream, leading to a phenomenon known as microchimerism, where fetal cells coexist with maternal cells. This exchange can also involve metabolites and nutrients that influence the mother's immune system and overall health.

Generally, the younger the mother, the better for both mother and baby
