The newborn’s struggle to hold back energy is actually infant colic, which is a normal problem during infant development, so parents should make it clear that this crying is not a symptom of disease. The infant should be kept in a comfortable position as much as possible and assisted to have a smooth bowel movement to improve the discomfort and thus relieve the crying. In addition to colic, hunger, bowel movements, and changes in body temperature can also cause crying. If the above causes are ruled out and the baby still cries, it may be due to intestinal spasms and the abdomen can be gently massaged to relieve the symptoms.
