The 3-3-3 rule for colic, also known as Wessel's criteria, helps define infantile colic based on crying patterns. It is a diagnostic criteria proposed by Wessel to identify colic. [[14]].
Here's a breakdown of the "Rule of 3":
- Crying lasts for at least 3 hours a day.
- Occurs for 3 or more days a week.
- Persists for over 3 weeks.
In essence, if an infant exhibits excessive crying and fussiness that meets all three of these criteria, they are often diagnosed with colic.
