Colic Signs and Symptoms
Most babies will cry less when they are held, fed, and given attention. These things may not work for babies who have colic. When they are crying, they may clench their fists and stiffen their stomach and legs. Some babies arch their back, while others pull up their legs to their stomach.
Vomiting, diarrhea, fever, or blood or mucus in the stool is not a symptom of colic. If your baby has any of these symptoms, he or she needs to be checked by a doctor.
