All babies cry, but how much is too much?

 All babies cry. The average duration of crying during the first three months of life ranges from 68 to 133 minutes per day. The duration of crying is greatest during the first six weeks of life and declines after eight to nine weeks. During the first three months of life, they cry more than at any other time. But when a baby who is healthy cries for more than three hours a day, more than three days a week, a health care provider may say the baby has colic.
