Persistent crying is one of the most common reasons why desperate parents are seeking professional help in the first year of baby´s life.
Any parent will be familiar with a "colic period" during the first 3 month, which is usually transitory and not related to any further problems for child or parents.
Persistent crying is defined as "fussing" or crying for
-
more than 3 hours per day
-
more than 3 days a week
-
in the past 3 weeks
This condition is found in about 10-15 % of all infants during the first 3 month of life, but persists in a significant percentage and can cause severe distress for the family life and parent-child relationship.
