" Everyone gets a stomachache from time to time, but up to 10 percent of kids have chronic constipation, says Maria Oliva-Hemker, MD , chief of pediatric gastroenterology at Johns Hopkins Children&amp;#039;s Center. If your child complains of straining\u2014or if he&amp;#039;s having bowel movements only three times a week\u2014try to get him to eat more fiber-rich produce and whole grains. But if the problem persists for three months\u2014or he&amp;#039;s in pain\u2014consult your pediatrician. He may test for celiac disease, food allergies or thyroid problems. After ruling those out, he may suggest taking laxatives or seeing a specialist.    "^^<http://www.w3.org/2001/XMLSchema#string>
