Some behavioral differences between human sexes appear in infancy and are linked in part to prenatal hormone exposure rather than socialization alone.

Is it true that some behavioral differences between human sexes appear in infancy and are linked in part to prenatal hormone exposure rather than socialization alone?

Unclear. The retrieved items offer only partial support: a meta-analysis reports adult sex differences in sensation seeking and punishment sensitivity consistent with biological accounts, and a Wikipedia article states that prenatal androgen exposure influences childhood sex-typed behavior. None of the items addresses infancy specifically or directly ties prenatal hormone exposure to infant behavioral differences.
