Intestinal colic is a common phenomenon, but generally does not occur every day. Babies with intestinal colic may exhibit symptoms such as paroxysmal crying, decreased appetite, and restless sleep at night. Intestinal colic typically occurs around 6 months of age, when the baby's gastrointestinal function is not yet fully developed. At this age, the baby begins to eat solid foods, and some of these foods are hard to digest, leading to gassiness. When a baby experiences intestinal gas, it can lead to intestinal colic. You can perform gas-relief exercises for the baby or massage the abdomen clockwise, which helps expel the gas from the intestines. Additionally, you can administer probiotics orally to adjust the gut flora. If the intestinal gassiness is significant, some medications can be taken orally to absorb the excess gas in the intestines and relieve the colic. Another method to try is holding the baby in an "airplane" position to alleviate discomfort.
