If your child is experiencing diarrhea, it's important to keep them well hydrated by encouraging them to drink fluids. You may want to offer light foods such as soups, broth, crackers, and rice while avoiding heavy and sugary foods like red meat and undiluted fruit juices. It's also important to monitor your child's symptoms and seek medical attention if they develop a fever lasting more than 3 days or are unable to drink or eat. Remember to consult a healthcare professional for further guidance.
