Famous quotes containing the words parity and/or pattern:
“The U.S. is becoming an increasingly fatherless society. A generation ago, an American child could reasonably expect to grow up with his or her father. Today an American child can reasonably expect not to. Fatherlessness is now approaching a rough parity with fatherhood as a defining feature of American childhood.”
—David Blankenhorn (20th century)
“A two-week-old infant cries an average of one and a half hours every day. This increases to approximately three hours per day when the child is about six weeks old. By the time children are twelve weeks old, their daily crying has decreased dramatically and averages less than one hour. This same basic pattern of crying is present among children from a wide range of cultures throughout the world. It appears to be wired into the nervous system of our species.”
—Lawrence Kutner (20th century)
