Gas may rumble in the stomach and be passed through the rectum. No one knows what causes such attacks. They often come at the same time every day. At other times of the day the infant is happy, alert, eats well and gains weight. If your baby has such an attack, holding him or her across your knees on the stomach often will give some comfort.
Some colicky babies cry less if they are kept in motion.
Try rocking or pushing in a stroller. There is little you can do except try to comfort the baby until the attack stops. Remember that if your baby has colic, it does not interfere with his or her general health and growth. Your baby should grow out of it by the time he or she is 12 to 16 weeks old. Remind everyone that it is not the baby's fault, it is not your fault, and the baby will get over it.
