I think that if the woman is type O+ and the husband is AB+ dun lang magkakameron positively ng incompatibilty towards the mother blood and the baby's blood kase mag kaiba ng dugo si mother at baby. pag AB+ and O+ kase the baby should be A+ or B+. if the mother is AB+ and the father is O+ then the mother and child have compatibility of the blood and can able to help the child with redblood cells.
PS: This is just based on the articles I've read. better check for OB paren. Godbless us all ❤
