How much do newborns know?

Newborns have limited knowledge and understanding of the world around them. However, they are born with innate abilities, such as recognizing their mother's voice and distinguishing between different smells. Their sensory systems are active, allowing them to respond to stimuli like light and sound, but their cognitive development and understanding of concepts will grow significantly in the following months and years. Overall, while they may not "know" much in a traditional sense, they are equipped with the tools to begin exploring and learning from their environment.
