1. Colic does not indicate something's wrong.
The standard, yet somewhat arbitrary, definition of colic is a total of three hours or more a day of irritability, fussiness or crying on more than three days a week for more than three weeks.
"Like height in adults, babies fall along a continuum," says Ron Barr, M.D.C.M., F.R.C.P.C., an infant-behavior researcher and professor of pediatrics at the University of British Columbia. "Some cry a little and some cry a lot. It doesn't mean there's something wrong with the baby."
