Famous quotes containing the word basic:
“Our basic ideas about how to parent are encrusted with deeply felt emotions and many myths. One of the myths of parenting is that it is always fun and games, joy and delight. Everyone who has been a parent will testify that it is also anxiety, strife, frustration, and even hostility. Thus most major parenting- education formats deal with parental emotions and attitudes and, to a greater or lesser extent, advocate that the emotional component is more important than the knowledge.”
—Bettye M. Caldwell (20th century)
