What are the symptoms of colic?

Standard Definition: Early on, researchers came up with a standard description to bring some uniformity in assessment & proposed treatments. The rule of 3's describes crying for at least 3 hrs/day;3days/wk in the first 3 months of life. It implys crying when no physical need (feeding) & no medical illness (reflux, ear infection, uti) were detected of thorough evaluation. It often occurred more in the afternoons.

Crying...: Uncontrollably and repeatedly, often at the same time of day, and for no apparent reason. It can look like there's a lot of pain, even if there isn't. If you have found a reason for it, it's not called colic any more. When you find the reason, you deal with the reason; then the crying stops.
