My 3 year old passed a large bm (hard) and is now having what seem like painful diarrhea fits for the last hr. anything other then hydrate?

See Your Doctor Now: Children at this age are prone to constipation due to inadequate dietary fiber/water intake. The passage of a large, hard BM followed by loose stools with pain suggests child may be backed up with stool. Hard stools occur after being held too long which is also common in toddlers. Once passed, soft accumulated stool can pass. Can be chronic problem. See doctor now for evaluation and management
