  • the blood types don't mix. The child usually gets the mom's blood type

  • Don't just look at your blood type...DH and I are both O pos and DD is O neg (only 1 O neg in our families-my FIL).

  • Plus, rarely, a child will have a blood type that isn't either the mom's or the dad's.

  • It is definitely more complicated than you would think, as Brawnwyn indicated. For example, my mother is B negative and my father is A positive. I am O positive.

  • I'm A- and my husband is A+. One kid is A- the other is O-. At the delivery they had to give me a special drug so the next pregnancy if the baby would have been a + blood type my body wouldn't reject the baby. It happens if the parents are different + or - and not the A,B, O or AB. Your ob/gyn could answer that question for you.

  • It depends on what the secondary genes are really. Blood types are made up of two genes. So someone with A blood could have AA or AO blood. Someone with O blood can only have OO blood though. As for the +, it could be ++ or +-. So it is complicated and hard to tell. My wife as A+ blood and I have O+ blood, our kids have O+ blood.
