„Economically disadvantaged and wealthy parents exhibit large and systematic differences in parenting practices. From birth to age two, non-poor children are more likely than poor children to be caressed, kissed, or hugged by their mother, and they are less likely to be spanked. Non-poor birth-to-two-year-olds also have greater access to children’s books and are more likely to be read to than their poor counterparts. These disparities have significant consequences, as children who experience responsive and stimulating parental care tend to score higher on assessments of motor, social, emotional, literacy, and numeracy skills than those who do not.“
