It was probably something that he ate. My girls had a barium swallow and theirs was white for a day or 2. I googled it and it said it probably is something they ate but it also said this so definitely see a doctor if it happens often.
The usual cause of a white bowel movement is a malfunctioning liver or biliary system. It should be noted that bile is what causes our stools to be colored brown, which is the natural color of stools. A white bowel movement would usually indicate blocked bile ducts in your liver. An indicator of blocked bile ducts aside from white bowel movement will be pain in the upper right part of your stomach.
