Snap judgment

Both?

would there just be a fetus there or maybe the baby would be like half dusted cause the baby and mother share certain things?

Babies have a different circulatory system than the mother. The placenta transfers oxygen and removes waste from the baby’s blood....but they don’t share blood. Sooo...maybe not?

but they do share stem cells. If the mother receives physical trauma the baby will send stem cells to help repair it.
