I see that you are offline. Traditionally it was recommended that children have the BRAT diet- bread, rice, applesauce, toast. However, BRAT diet foods are low in fiber, protein, and fat, the diet lacks enough nutrition to help a child's gastrointestinal tract recover. The American Academy of Pediatrics now recommends that kids resume eating a normal, well-balanced diet
appropriate for their age within 24 hours of getting sick. That diet should include a mix of fruits, vegetables, meat, yogurt, and complex carbohydrates.
So, bananas are great to help thicken up the stool, but it is very important that he keeps up with his hydration. He may need pedialyte, or another type of oral rehydration. Bulking agents, such as starches, fresh fruits, and vegetables sometimes help create more solid stool. Fruit juices can loosen stool.
Go to the ER if he has:
Your child is much less active than normal (not sitting up at all or looking around)
Diarrhea contains blood or mucus
Diarrhea is accompanied by multiple vomiting
, or abdominal cramping
Dry and sticky mouth
Has not urinated for 6 hours
No tears when crying
Call your pediatrician if:
Diarrhea is severe, or lasts longer than 2 to 3 days
Diarrhea keeps returning, or the child is losing weight
