What Cause Colic?

There are four theories as the answer of what cause colic:

Theory of Stomach Problems
Gas, constipation, and overactive intestines are cited most frequently in the literature as the answer of what cause colic. This is understandable considering the fact that all three of these factors can unquestionably lead to feeling of discomfort, causing a baby to cry. Two different types of stomach problem are cited in the literature: problems with the baby's immature digestive system or intestinal illness, such as stomach acid reflux or food intolerance/allergy.

Brain Development
This theory states that when a baby's nervous system is not fully matured, it can cause the baby to feel overwhelmed, and as a result the baby cries. It made sense that colic baby has been in the womb for nine months with minimal stimulation. Once born, they are faced with new sounds, smells, sights, and touch. And this is what cause colic.

Maternal Anxiety
Mothers who are anxious elicit the same anxious response in their babies. In other words, the anxious mother transfers her anxieties onto her baby, which in turn causes the infant to cry. Many parents find this theory upsetting to read about. It is the one theory that feeds right into the mothers of a colicky infant's already existing insecurities. Normally, most mothers don't want to accept this cause because accepting it means they are fully to blame.

Baby's Temperament
Sensitive babies will inevitably respond more intensely to things that cause them distress, and as a result get upset and cry more.
