The term "Sippys method" refers to a technique known as "graduated extinction" or "controlled crying". This method is commonly used by parents to help their babies establish a healthy sleep routine. By gradually reducing parental intervention during nighttime awakenings, the Sippys method encourages infants to self-soothe and fall back to sleep independently. While controversial, proponents argue that it can promote better sleep habits for both infants and parents. Synonyms for the Sippys method therefore include "graduated extinction", "controlled crying", or even "self-soothing technique". These terms all describe the same approach of gradually reducing parental intervention during sleep time to foster independent sleeping skills.
