The best thing you can give a toddler with diarrhea is an oral rehydration solution (ORS) like Pedialyte, along with their normal diet. Most toddler diarrhea is caused by a virus and resolves on its own within a few days, so the real priority is replacing lost fluids and keeping your child nourished while their gut recovers. Over-the-counter anti-diarrheal medications are not safe for young children.
Oral Rehydration Solution Is the First Priority
Diarrhea pulls water and electrolytes out of your toddler’s body fast. Plain water doesn’t replace the salts and sugars lost, so an oral rehydration solution is the go-to recommendation. Products like Pedialyte, Enfalyte, or store-brand equivalents contain a precise balance of sodium, potassium, and glucose designed to help the intestines absorb fluid efficiently.
For a toddler showing no signs of dehydration, offer 4 to 8 ounces of ORS after each watery stool. If your child already seems mildly dehydrated (dry lips, fewer wet diapers, fussiness), the target is roughly 50 to 100 milliliters per kilogram of body weight over three to four hours. For a 25-pound toddler, that works out to about 19 to 38 ounces sipped steadily over that window. If your child resists drinking, try offering small amounts with a syringe or medicine dropper, starting with a teaspoon at a time and gradually increasing as they tolerate it.
Keep Feeding Normal Foods
One of the most common mistakes parents make is withholding food. Starving the gut doesn’t help it heal. Current guidelines are clear: children should continue eating their usual diet during diarrhea episodes, and withholding food for more than 24 hours is considered inappropriate. If your toddler is breastfeeding, keep nursing on demand. Formula-fed toddlers should stay on their regular formula. You generally don’t need to switch to a lactose-free version.
You may have heard of the BRAT diet (bananas, rice, applesauce, toast). While these foods are gentle and reasonable options, relying on them exclusively for days can leave your toddler short on calories and protein during a time when their body needs both. Instead, offer a variety of foods: rice, potatoes, noodles, crackers, bananas, oat cereal, yogurt, cooked vegetables, soup, and fresh fruits. A mix of starches and proteins supports recovery better than a restrictive diet.
Foods and Drinks to Avoid
Anything high in sugar can actually make diarrhea worse. Sugar draws extra fluid into the intestines, making stools more watery. That means skipping soda, sports drinks, gelatin desserts, presweetened cereals, and undiluted fruit juice. Apple juice is a particularly common culprit. In fact, excessive juice consumption is so frequently linked to loose stools in young children that pediatricians have a name for it: “toddler’s diarrhea.” It often resolves simply by cutting out juice. Sugar substitutes like sorbitol have the same fluid-pulling effect and should also be avoided. Fatty foods can slow stomach emptying and cause discomfort, so hold off on greasy or fried items until your child is feeling better.
Probiotics May Help Shorten Recovery
Certain probiotic strains can reduce how long diarrhea lasts. A 2025 review in Frontiers in Pediatrics found that Saccharomyces boulardii (a yeast-based probiotic sold under brand names like Florastor Kids) significantly shortened diarrhea duration compared to placebo. Another strain, Limosilactobacillus reuteri, also showed a meaningful reduction. Lactobacillus rhamnosus (the strain in Culturelle Kids) was effective at reducing the number of children still experiencing diarrhea by the end of a study period, though its effect on shortening duration was less clear.
Probiotics aren’t a cure, but they’re safe for toddlers and may trim a day or so off the illness. Look for products specifically formulated for children and check the label for one of these strains.
Zinc Supplements Can Reduce Severity
The World Health Organization recommends giving children with diarrhea 20 milligrams of zinc daily for 10 to 14 days (10 milligrams for babies under six months). Zinc helps the intestinal lining repair itself and can reduce both the severity and duration of the episode. Zinc supplements for children are available in dissolvable tablet or liquid form. This recommendation is especially emphasized in developing countries where zinc deficiency is common, but it’s a safe and inexpensive option worth discussing with your pediatrician regardless of where you live.
Medications to Avoid
Do not give your toddler anti-diarrheal medications. Loperamide (Imodium) is not recommended for infants and children. Bismuth subsalicylate (Pepto-Bismol) should not be used in children under 12. It contains a salicylate compound related to aspirin, which carries a risk of Reye’s syndrome, a rare but serious condition, especially in children with a fever or those recovering from a viral illness like the flu or chickenpox. Children are also more sensitive to salicylate side effects when they’re already dehydrated from vomiting or diarrhea.
The goal isn’t to stop diarrhea immediately. Diarrhea is the body’s way of clearing an infection. Your job is to keep your toddler hydrated and nourished while the illness runs its course.
How to Spot Dehydration
Dehydration is the main danger of toddler diarrhea, not the diarrhea itself. Mild dehydration looks like a slightly dry mouth, slightly fewer wet diapers, and increased thirst. You can manage this at home with oral rehydration solution.
Moderate dehydration is more concerning. Signs include a dry mouth with no moisture on the inner cheeks, sunken eyes, no tears when crying, very little urine output, and noticeable lethargy. If you gently pinch the skin on the back of your toddler’s hand and it doesn’t snap back immediately, that’s another warning sign. Severe dehydration adds rapid breathing, a fast and weak pulse, cold or mottled-looking skin, and extreme drowsiness or unresponsiveness. Moderate to severe dehydration requires medical attention, as your child may need fluids given in a clinical setting.
When Diarrhea Needs Medical Attention
Most viral diarrhea clears up within two to three days. You should contact your child’s doctor if symptoms worsen or persist beyond that window. Seek prompt medical evaluation if you notice any of the following:
- Blood in the stool or vomit
- Green (bilious) vomit
- High fever, especially above 102.2°F (39°C)
- Severe or localized abdominal pain (not just general cramps)
- A bloated, distended abdomen
- More than five watery stools in 24 hours, particularly in younger toddlers
- Signs of moderate dehydration that aren’t improving with oral rehydration
- Your child looks very unwell or is unusually drowsy
If diarrhea continues beyond seven days, a stool sample may be needed to check for bacterial or parasitic causes rather than a simple virus. Recent travel increases the likelihood of a non-viral cause worth investigating.
