The three biggest challenges of caring for new babies are feeding, calming crying and getting sleep. Over the past 60 years, support for breastfeeding has increased significantly (as has the availability of formula). But little advance has been made in the study and support of parents with fussy babies. In fact, parenting and professional guides have traditionally taught that colic is a mysterious problem with no remedy. Desperate and weary parents have been advised to deposit their crying babies alone in cribs to scream themselves to sleep.
