my grandson 2 years old has recently had a bug with symptoms of vomiting that lasted 2 days, and diarrhea that has lasted 4 to 5 days. My question is the diarrhea is watery and tan in color. Mild odor. He doesnt appear to feel bad. Eating has tapered off about 40% less than usual. What should we do. There is no fever. Drinks ok. Still takes a bottle, so he has had milk, whole in bottle. x 1 a day.
