My husband is O- and I'm B+. I have been told once that if a certain type of blood (B+)is mixed with O- the child could become defective . Is any thing about this true?

Blood Types in Pregnancy

You are Rh positive and you husband is Rh negative. Problems with the Rh factor occur when the mother's Rh factor is negative and the baby's is positive.

I think you are asking about incompatible Rh factors. It would be an issue if you were Rh negative and your husband RH positive, as the baby could then be Rh+ and the baby's blood would then not be compatible with yours. But in your case, since you're Rh +, there is no problem.

From the WebMD web site:

"Rh blood type is especially important for pregnant women. A potential problem arises when a woman who has Rh-negative blood becomes pregnant with a baby (fetus) that has Rh-positive blood. This is called Rh incompatibility. If the blood of an Rh-positive baby mixes with the blood of an Rh-negative woman during pregnancy or delivery, the mother's immune system produces antibodies. This antibody response is called Rh sensitization and, depending on when it occurs, can destroy the baby's red blood cells.

"Rh sensitization does not usually affect the health of the baby during the pregnancy in which the sensitization occurs. However, the baby of a future pregnancy is more likely to be affected if the baby's blood type is Rh-positive. Once sensitization has occurred, the baby can develop mild to severe problems (called Rh disease, hemolytic disease of the newborn, or erythroblastosis fetalis). If untreated, complications from sensitization can, in rare cases, lead to the death of an Rh-positive baby.

"An Rh test is done in early pregnancy to detect a woman's blood type. If she is Rh-negative, she can receive an antibody injection called Rh immune globulin (such as RhoGAM) that almost always prevents sensitization from occurring. Problems arising from Rh sensitization have become very rare since the Rh immune globulin injection was developed."
