Baby: Can start from the very beginning, where they have their startle (Moro) reflex. Doesn't have to be to all sounds and reacting all the time.

Immediately: Studies show a preference for mothers voice by age 3 hours and dads by the end of the day. These are often a subtle like the flicker of an eyelid.
