To be a Feotus the baby must still be in the womb and is therefore still connected to its mother via the Placenta from which it receives oxygen and nutrients. Reb blood cells do not travel across the membranes of the placenta and therefore cannot pass between mother and foetus. This is because the placenta it effectively a loarge capillary bed from the foetus aligned with one from the mother. Just like in any other cappilary the red blood cells are far too large to pass across the vessel walls.
