Bay is 6 months and have been crying frantically for the past hour. ?

Need more info: Babies cry often, but by 6 months you know your child and you sound worried. If baby was happy and ate well today, it is unlikely serious & try calming. Stomachache can be caused by new foods, constipation or cramps with diarrhea. Be sure clothing isn't pinching or other minor trauma. If baby is sick with a fever or a bad cold, an ear infection or sore throat is painful. Call his doctor.
