Between 3 to 5 months of age, babies start to link which two senses together?

Between the ages of 3 to 5 months, infants begin to show significant integration of their sensory experiences, particularly blending sight and sound. At this stage of development, babies are more responsive to visual stimuli and are able to coordinate their visual observations with auditory input. For example, they may turn their heads towards a sound they see, reflecting their ability to connect auditory information with what they are observing visually. This integration is crucial for their overall cognitive development as it lays the foundation for learning more complex interactions in their environment.

While touch and sound, taste and smell, and vision and movement are important in babies' sensory development, the notable synchronization of sight and sound at this age marks a pivotal advance in their ability to process and understand the world around them.
