Colicky infants may have a hard abdomen, get red in the face, and curl their legs up.
However, excessive crying, colicky behavior, and a baby that refuses to sleep are behaviors which should be addressed immediately with your doctor.
Moreover, in spite of apparent abdominal pain, colicky infants eat well and gain weight normally.
When colicky babies appear inconsolable, sometimes the only way to comfort them is to carry them close to your body.
The earliest symptoms are slight gastric disorders, loss of appetite and general malaise, followed later by colicky pains, irritation of eyelids and skin eruptions.
