Most of the time, the cause of the baby's colic cannot be determined, and it can't be prevented. Proper feeding techniques and appropriate diet can be helpful.
Colic does not have any adverse, long-term effects. Colicky infants can cause high levels of stress in their parents. This can place the infant at risk of being abused by a parent or other caregiver. This is more likely if the caregiver is socially isolated and has little help in dealing with the baby's crying.
Colic is not contagious and poses no risk to others.
