“When pregnant, the cells of the baby migrate into the mothers bloodstream and then circle back into the baby, it’s called “fetal-maternal microchimerism”.⁠

For 41 weeks, the cells circulate and merge backwards and forwards, and after the baby is born, many of these cells stay in the mother’s body, leaving a permanent imprint in the mothers tissues, bones, brain, and skin, and often stay there for decades. Every single child a mother has afterwards will leave a similar imprint on her body, too.

Even if a pregnancy doesn't go to full term or if you have an abortion, these cells still migrate into your bloodstream.

Research has shown that if a mother's heart is injured, fetal cells will rush to the site of the injury and change into different types of cells that specialize in mending the heart.

The baby helps repair the mother, while the mother builds the baby.

How cool is that?

This is often why certain illnesses vanish while pregnant.
