What does the fetus know and how does she know it?

Fetuses have a remarkable ability to perceive and respond to their environment, even before birth. They can hear external sounds, such as their mother's voice and music, and can also sense light and movement. This knowledge is acquired through sensory experiences in the womb, where they respond to stimuli via reflexes and changes in heart rate. Research suggests that these early experiences may shape their preferences and behaviors after birth.
