I’d replace “human” with “mammalian”—most young mammals share a similar set of traits, even those that aren’t constrained as we are by big brains and a pelvic girdle adapted to walking upright. That seems to suggest a more basal cuteness response; I believe the biology term is “baby schema”.
Not terribly relevant to your point, but it’s likely human sense of cuteness is based on what babies do rather than the other way around.

Other than that, yeah.
