Dr. Jay Schwartz treats colic in infants, which is defined as crying intensely for more than three hours a day, three or more days a week, over at least three weeks. Colicky infants often cry in the evenings and their faces become red and tense, though the cause of their crying cannot be identified. While research has not determined the exact causes of colic, it is believed to be related to an immature digestive system and sometimes disappears after the infant passes gas or has a bowel movement, with most cases resolving by four months.

2. Introduction
 A board certified pediatrician, Dr. Jay Schwartz operates Collin County
Pediatrics in Frisco, Texas. Dr. Jay Schwartz treats a wide range of
illnesses in newborns and infants, such as colic.
Colicky infants cry intensely and often for long periods of time, most
frequently in the evening. Doctors define colic as crying for longer than
three hours a day, three or more days per week, over a period of three
or more weeks.
As opposed to babies crying normally, colicky infants sound like they
are screaming or experiencing pain. Their faces become red, with pale
skin near the mouth, while their bodies become tense and stiff. Crying
occurs without an obvious cause such as hunger or a diaper in need of
changing.

3. Colic
 The babies are very fussy, even when the crying has lessened.
Colic distresses parents because their efforts to console their child bring
no relief. However, symptoms sometimes disappear when the infant
passes gas or experiences a bowel movement.
Research has yet to discover the causes of colic, nor can it explain its
onset at roughly six weeks and its reduction after three to four months.
Some reasons have been proposed, such as a still-developing digestive
tract with an imbalance of beneficial bacteria. Food allergies,
underfeeding and overfeeding, and infrequent burping may contribute,
as can stress in the family. It's also believed that colic might be caused
by an early form of childhood migraines.
