Well, I think you would need to go to your babh's doctor to get diagnosed for sure. Although in my CIMT course I learned about what commonly defines colic:
Colic | "Rule of Three"
Crying for more than three hours per day
For more than three days per week
For longer than three weeks in an infant who is well-fed and otherwise healthy
Also here's a link to a really
good article with more information about colic:
