It's complicated: There are a lot of varients and the maternal blood cells and antibodies and fetal cells are all present at birth. So, you can't really say what the blood type is at birth on varient, but in the 95%+ who don't have it, you can definitely ignore it. Then, testing of parents and child would be important for pregnancies or transfusions. Most are rh+. negatives react, varients MIGHT react to rh+ .
