Famous quotes containing the word period:
“Unless your baby becomes uncomfortable and tries to push away, don’t worry that you’re cuddling too much. That way, when she reaches adolescence and goes through a normal period of being terribly embarrassed even to be seen with you in public, you’ll have some memories to tide you over until she comes around again.”
—Lawrence Kutner (20th century)
