It can be difficult to determine if your baby has colic, but certain signs and symptoms may indicate they are suffering from this condition. These include periods of intense and inconsolable crying, arching their back or legs while crying, clenching their fists, facial grimacing and/or a reddened face during periods of distress. Babies with colic may also have irregular sleep patterns and seem to pass gas more often than normal. If you suspect your baby may have colic, it is important to consult your pediatrician for proper diagnosis and treatment.
