Children’s Hospital at London Health Sciences Centre (LHSC) has an campaign every October for knitters to knit or crochet purple colored newborn caps for baby boys and girls.
Why purple? The Period of PURPLE Crying is something that many babies experience and is characterized often by periods of inconsolable crying. The purple hats remind parents and caregivers that babies cry, sometimes for hours and that this is normal. Never shake a baby. More information on the Period of PURPLE Crying can be found here.
There are many patterns available. Be sure to check the guidelines on that page for materials, sizes, and other information.
