The major colic baby symptom is continuous crying for some periods of time, and the sound of the cry is much more intense than that of other infants. A colic cry is often described as a piercing, relentless scream. It can stop as abruptly as it starts and is often heard during or immediately after a feeding, especially in cases when it is due to acid reflux. Although this crying could be happened at any time, it is usually the worse in the evening. Colic baby may lift his head, draw his legs up to their tummy, become red in the face and pass wind. Some babies refuse to eat. Difficult to stay asleep is also very common.

Colic is diagnosed by the "rule of threes" - if a baby cries at least three hours a day, three days per week, for three weeks in a row, then that baby is considered to be suffering from colic. Colic usually starts when the baby is two weeks old and ends when the baby is 100 days old, which is approximately three and a half months of age. In addition, premature baby is no more likely to suffer colic than a full term baby. The colic baby sounds as tough he is in tremendous pain. His face may be twisted and strained, causing onlookers to be highly concerned.

Normally, colic (except due to acid reflux problem) is not a serious condition. Research shows that babies with colic continue to eat and gain weight normally, despite the crying. The main problem with the condition is the stress and anxiety it creates within the home. Parents and other family members may find it difficult to cope with the continuous crying, so it's important to have support now and then.
Each baby will show different colic symptoms. Some may show a number of symptoms while some will only show one.

Below are some of the most common colic baby symptoms.

-They do not generally cry himself to sleep but instead continue to cry relentlessly, sometimes for hours.
-They do not tend to wind down; instead they tend to wind up and work themselves into frenzy.
-They do not always follow a pattern. What calms them at a given moment may excite them at another.
-Unlike other infants, when crying begins the colicky infant will rarely stop crying on his own, so waiting is out usually does not work. Instead, intervening quickly is helpful.
