Colic is a word that is often used for a baby who cries for any length of time, but did you know that it’s normal for babies to have a fussy period every day, often called the witching hour?  While it’s distressing for any parent to hear her baby cry, sometimes understanding that the behavior is a normal part of infant development can be helpful.  However, there are times when the behavior may be caused by something else, and even though the cause isn’t always immediately understood, there are measures that can be taken to reduce the symptoms of colic.
