What is actually happening is that he is starting to learn to listen. He can select certain sounds and memorize them. When he hears that sound again, he can match it with the one he has heard before. These skills are basic to all learning.
At the same time these early hearing and language skills get under way, the child begins to practice making sounds. His first sounds are the discomfort sounds. These sounds are heard when he is not quiet or sleeping. These sounds mean nothing to him yet. To his mother they say he is wet, uncomfortable, or hungry.
Within the babys first month, another sound appears: the comfort sounds. These are different from the discomfort sounds. As the child grows, his comfort sounds will use more of the vowels and consonants and rhythms which he will later use. These sounds will come together to form the first word. This special event will be long remembered by the proud parents.
