Colic is when otherwise healthy babies cry for seemingly unknown reasons. Babies with colicky behavior will cry for hours with no end in sight. They are otherwise well and comfortable. This can be extremely difficult for parents, especially if this is your first child. Pediatricians do not agree about what exactly causes colic. Something that crying actually causes gas issues because your baby is swallowing air. Other doctors think it is just an adjustment period to life outside of mom. Babies are difficult to study because they grow so fast and cannot tell us what is wrong.
