The best thing to feed a toddler with diarrhea is a normal, age-appropriate diet with a focus on bland, easy-to-digest foods and plenty of fluids. The old advice to restrict your child to bananas, rice, applesauce, and toast (the BRAT diet) is outdated. The American Academy of Pediatrics no longer recommends a strict BRAT diet because it’s too low in nutrients and can actually slow recovery if followed for more than 24 hours.
Your main priorities are keeping your toddler hydrated and getting calories back in as soon as they’re willing to eat. Here’s how to do both.
Fluids Come First
Diarrhea pulls water and electrolytes out of your child’s body fast. Replacing those losses is more urgent than getting food in. An oral rehydration solution (sold as Pedialyte and similar brands) is the gold standard because it contains a precise balance of glucose and sodium that helps the gut absorb fluid far more effectively than water alone. For mild dehydration, the general guideline is about 50 mL per kilogram of body weight over four hours. For a 25-pound toddler, that works out to roughly 20 ounces sipped gradually over four hours. After each watery stool, offer an extra 3 to 8 ounces.
Sports drinks, soda, and fruit juice do not count as rehydration fluids. They contain too much sugar and not enough sodium. Juice is especially problematic: juices high in fructose and sorbitol (apple and pear juice in particular) cause incomplete sugar absorption in the gut, which pulls more water into the intestines and can restart diarrhea just as your child is improving. If your toddler is still breastfeeding or on formula, keep those feedings going as usual. Breast milk and formula both provide fluid and calories, and there’s no reason to stop either one during a bout of diarrhea.
Foods That Are Gentle on the Gut
Once your toddler is willing to eat, offer small amounts of bland, soft foods from across the food groups. You’re not limited to four items. Good choices include:
- Grains: plain rice, oatmeal, noodles, toast, saltine crackers
- Protein: hard-boiled eggs, soft well-cooked chicken or turkey
- Vegetables: mashed potatoes, well-cooked carrots, green beans
- Fruits: bananas, applesauce, melon
- Dairy: yogurt with live cultures (more on regular milk below)
The goal is to return to a full, varied diet as quickly as your child can tolerate it. Bland foods are a starting point, not a destination. If your toddler wants scrambled eggs and toast for breakfast the morning after a rough night, that’s fine. Calories and protein help the intestinal lining repair itself, which is exactly what you want.
What to Avoid During Recovery
Some foods and drinks make diarrhea worse by drawing extra water into the intestines. Skip these until your toddler is fully back to normal:
- Fruit juice, especially apple and pear juice. The combination of fructose and sorbitol is poorly absorbed even in healthy guts and significantly worse during illness.
- Sugary drinks like soda, sweetened teas, and sports drinks.
- Fried or greasy foods, which are harder to digest and can trigger cramping.
- High-fiber raw vegetables and dried fruit, which speed up the gut when you want it to slow down.
- Candy, cookies, and other concentrated sweets.
The Dairy Question
You may have heard to avoid all dairy when your toddler has diarrhea. The reality is more nuanced. Infections that cause diarrhea can temporarily damage the lining of the small intestine, which is where your child produces the enzyme that breaks down lactose (the sugar in milk). This temporary lactose intolerance is common in infants and young children after a stomach bug.
Yogurt with live active cultures is generally well tolerated because the bacteria in the yogurt help break down lactose before it reaches the gut. Regular cow’s milk, on the other hand, may make diarrhea worse in some toddlers during the illness. If you notice that milk seems to trigger more loose stools, switch to a lactose-free version temporarily. The intolerance typically resolves within three to four weeks as the intestinal lining heals.
Probiotics Can Shorten the Illness
Giving your toddler a probiotic supplement during diarrhea is one of the few interventions that has solid evidence behind it. A large meta-analysis of 25 clinical trials involving over 5,000 children found that probiotics significantly reduced the overall duration of diarrhea and also shortened the duration of vomiting. By Day 2, children taking probiotics had notably fewer stools than those on placebo, and the benefit continued through Day 5.
Look for child-friendly probiotic products at your pharmacy. Yogurt with live cultures also provides beneficial bacteria, making it one of the most useful foods you can offer during recovery.
Skip the Over-the-Counter Medications
It’s tempting to reach for an anti-diarrheal medication to stop the loose stools, but the National Institutes of Health and pediatric guidelines recommend against giving over-the-counter anti-diarrheal drugs to toddlers and young children. These medications can cause serious side effects in small children and are not considered safe for this age group, particularly if your child has a fever or blood in their stool.
Signs of Dehydration to Watch For
Most toddler diarrhea runs its course in a few days with no lasting harm, but dehydration is the real danger. Keep an eye out for these warning signs:
- No wet diaper for three hours or more
- Dry mouth or cracked lips
- No tears when crying
- Sunken eyes or a sunken soft spot on the skull
- Skin that stays pinched or tented when you gently squeeze it
- Unusual sleepiness, limpness, or irritability
Seek medical attention if your toddler has had diarrhea for 24 hours or more, can’t keep fluids down, has bloody or black stool, or develops a fever of 102°F or higher. A rapid heart rate or extreme fussiness that you can’t soothe also warrants a call.
A Typical Recovery Day
Viral gastroenteritis, the most common cause of toddler diarrhea, usually lasts three to seven days. On the first day or two, your child may refuse food entirely. That’s okay. Focus on small, frequent sips of oral rehydration solution and continue breast milk or formula. As appetite returns, start with whatever bland food your toddler will accept, even if it’s just a few bites of banana or a handful of crackers. By day three or four, most toddlers are ready to eat close to their normal diet. Let your child’s appetite guide you, and don’t force food. The intestines are healing, and pushing too much too fast can trigger more discomfort.
Within a week, most children are back to their regular eating patterns. Stools may remain a bit looser than normal for a few days after that, which is expected as the gut finishes repairing itself.
