PIERRE - A new program in South Dakota is educating parents about a period in a baby's life when they may cry a lot.

Called "The Period of PURPLE Crying," the program teaches parents about the period from about 2 weeks to 5 to 6 months when some babies cry a lot.

The program includes a 10-minute video and brochure. It's given to all new parents and is required to be viewed at a hospital prior to being discharged.

Jackley says teaching parents about this common growth period in infants will help prevent shaken baby syndrome.

The letters in PURPLE each stand for characteristics parents may be watch for in their babies.
