I believe you’re using “soft”v. “hard” to distinguish what the author calls “inter generational” v “trans generational”. Using this distinction, “soft” epigenetics in your example is just epigenetics. The fetus responding to an external stressor which happens to be induced by a stressor on the mother. And in the case of female fetuses who have a fixed number of eggs for life, can impact those and therefore one more generation.
