Answer to Question 2
At birth, the human brain is remarkably unfinished. Most of the 100 billion neurons or brain cells are not yet connected. As a child matures, the number of synapse connections increases, and the message-receiving dendrite branches grow larger and heavier. This neural wiring (and the simultaneous maturation of the hippocampus and other areas of the brain responsible for memory storage and retrieval) allows children to begin to consistently link sounds to objects. Neural readiness, in combination with countless hours of sound play and verbal exchanges with loving caregivers, allows most children to begin speaking their first words.
