What are the symptoms of colic in an 18-day-old baby?

Patient's question:

No

Doctor's answer:

According to research, approximately 10 to 20% of infants have experienced colic. It usually begins in babies aged two to four weeks and peaks between four to six weeks. Typically, it improves on its own by the age of four to six months at the latest.
When colic occurs, the characteristics are often repeated episodes of abdominal pain and crying in the baby. The symptoms may be milder during the day, but at night, there are intermittent sudden outbursts of loud crying, and the baby may cry continuously for three to four hours, making it difficult to calm them down.
At this stage, most affected infants may also exhibit restlessness, flushed faces, knees pulled up, and clenched fists or kicking legs. There is often bloating, known as "wind," which improves after the rapid intestinal movement subsides or the baby passes gas. Typically, the baby will calm down a few hours after an episode.
The four main symptoms of infant colic are:
1. Crying and restlessness.
2. Reddish face.
3. Knees pulled up.
4. Clenched fists and kicking legs.
