Language, the way we express ourselves, is a vital part of learning. A baby learns his native tongue naturally by hearing speech around him. If the speech he hears is rapid, not clear and never directed at him then he learns slowly and speaks badly. A child of 2 or 3 years old who cant make his desires known or put his thoughts into words will usually become angry. His relationships with others will get worse.
