Why can't children get blood transfusions from their biological parents?
I'm not a biology teacher. We don't have an volunteer biology teachers on Jiskha. From what I can find out, there are specific circumstances under which parents cannot donate blood to their children, but I don't know what they are. Generally, relatives may donate. Pay special attention to your text materials. They may explain those circumstances where parents should not donate to their children. "Google" your question into your search engine and see what you can find.
Follow prompts, then type your question into the appropriate box and see what you can find.
Basically, what I found was advice that parents and children should have their blood "matched" by a laboratory before donating. Attending physicians will advise.
For example, if AB and OO type parents have children, the children will only be BO or AO.
