what makes babies/young children prefer soft calm voices over deep manly voices?

Question

I’m not talking like why do they not like screaming but I mean why do they prefer the softer type of voices?

There are different theories to this, and some can overlap. The ones I lean towards are that 1) in-utero, where it’s warm and safe, you hear your mom’s voice more than anyone else’s, so you come to associate her voice with that comfort, and 2) that over human history mothers/women have done most of the child-rearing, so children have come to prefer their voices.
