“Talkative” (often college-educated) parents spoke 2,100 words to their child, on average. By contrast, parents from less verbal (and often less-educated) backgrounds spoke only 600 per hour, on average. If you add that up over the first thirty months, the child of “talkative” parents heard an estimated 48 million words spoken, compared to the disadvantaged child, who heard only 13 million. The most important time for the children to hear the words, the research suggests, is the first year of life.
