Famous quotes containing the word milestone:
“As your baby progresses from one milestone to the next, remember that he doesn’t really leave any of them behind. In order to grow and develop to his full potential he must continually build on and strengthen all of the steps that have gone before.”
—Stanley I. Greenspan (20th century)
“Every milestone of a firstborn is scrutinized, photographed, recorded, replayed, and retold by doting parents to admiring relatives and disinterested friends. . . . While subsequent children will strive to keep pace with siblings a few years their senior, the firstborn will always have a seemingly Herculean task of emulating his adult parents.”
—Marianne E. Neifert (20th century)
