Yakima Valley Memorial Hospital is offering a new class to help parents better understand the developmental stage in a baby’s life when they cry more than any other time (usually from 2 weeks of age until about 3-5 months). Doctors used to refer to this as colic, but the National Center on Shaken Baby Syndrome has coined this stage of development as “The Period of PURPLE Crying®.” PURPLE is an acronym—P stands for peak of crying, U for unexpected, R for resists soothing, P for pain-like face, L for Long lasting and E for evening , when this type of crying is most common. The Period of PURPLE Crying® program was developed by the to help parents understand and prepare themselves for what to expect during this time. Classes are from 1-2 p.m., February 9, March 9, and April 21, at Memorial’s Education Center. People can register for this class or find more information at 509-248-7322, or yakimamemorial.org/events.
