CB; Communication of language to the fetus is quintessentially ( as in "essentialist) human natural. Nothing unnatural about fetus hearing the mother and others. What is ur aversion to referring to this relationship , and group of social relations between the fetus and others as "natural" ? What is human nature ? It is especially the fetus' proto-language experience. This is precisely the unity of the human and the natural, human natural relations. Language is a uniquely human"natural" or human mammalian (mama) capacity most fully at the level of the fetus, in part because there is no way for the mother or others to convey the _historical_ content of the sounds the fetus hears. The fetus experiences them as an abstract pattern which its brain is _naturally_ especially capable of affinity for because it is a human fetus. It is the abstract phonology system of relationships between signs/symbols, the structure , in the sense of structural linguistics, not meaning or semantics that the fetus takes in. This abstract logical structure is the most natural, least specifically historical aspect of language. Only after birth does this being learn the semantical and historical content of "boy and girl."
Humans are naturally highly social. We are the social animals. So "social embeddedness" for humans is a critical part of our nature.
Be happy with the word "natural".
