I explicitly stated that experience of biologically delivering a child is affecting both of parents, NOT on a biological basis but strictly on the level of THE experience itself. I could have been clearer by stating "biologically delivered child by mother", instead of the "biological child", but I have not, in any sense, reffered to a biological child-father connection being relevant to anything. What may have confused you is that I stated that the idea of being biologically related to someone, has a mental effect that creates some emotional attachment - yes, due to the biological relation as a social construct. That was an additional idea to compare it to adopted cat/dog/child analogy.
