Hello, my name is Dr.Dorina Gurabardhi. I understand your concern.
Some advices that I can give to you are:
1)Make sure your child is drinking often. Frequent, small amounts work best.Allow your child to drink as much fluid as he or she wants. Encourage your child to drink extra fluids or suck on flavored ice pops, such as Popsicles.Do not give your child fruit juice or soda pop. Fruit juice and soda pop contain too much sugar and not enough of the essential minerals (electrolytes) that are being lost. Diet soda pop lacks calories that your child needs.
2)Cereal mixed with milk or water may also be used to replace lost fluids.
3)If your child still is not getting enough fluids, you can try an oral rehydration solution.
4)Give your child frequent small meals, at least 6 a day, while he or she is having
diarrhea.The best foods for your child are easily digestible foods, such as rice cereal, pasta, breads, cooked beans, mashed potatoes, cooked carrots, applesauce, and bananas.Pretzels or salty crackers can help your child replace the salt lost from diarrhea.
5)Foods containing large amounts of sugar or fat should be avoided.
Hope my answer was helpful, if you have any other questions I'll be glad to help, thanks!
