My friend Nancy gave me this link to help new parents remember that babies cry. Sometimes they cry so much the new parents don't know what to do. Sometimes those new parents shake their babies to make them stop.
This website and the efforts it promotes makes baby hats in all shades of purple to remind parents that it is ok for a baby to cry and that crying won't hurt them, but shaking them will.
I have made baby hats for my local hospital for years and am now going to include some purple ones with the website address so new parents can learn how to deal with a baby who cries and won't stop.
If you love to knit or crochet, maybe you will want to join the effort.
