A baby with diarrhea can turn an ordinary day into a long stretch of feeding, diaper changes, and worry. Your baby may be fussier than usual. Feedings may feel harder. And with every loose diaper, you may find yourself wondering what to offer next.
The good news is that you do not need to stop feeding your baby while they recover. Breastmilk, full strength formula, and the right fluids can help your baby stay hydrated and get the energy they need. For babies already eating solids, simple, nourishing foods can stay on the menu too.
This guide walks you through what to feed your baby with diarrhea, what to avoid, and the signs that mean it is time to call your pediatrician. For more support, you can also explore our baby diarrhea care guide.

What to Feed Your Baby During Diarrhea
Breastfeeding During Diarrhea
When your baby has diarrhea, breastfeeding can be one of the simplest things to continue. Breastmilk provides fluids, calories, and helpful antibodies while your baby’s body works through the illness.
You do not need to stop nursing because of loose stools. In fact, your baby may want to feed more often than usual. Offer the breast whenever your baby is hungry, and let them take what they can comfortably manage.
Keep breastfeeding on demand, even during diarrhea. Avoid replacing breastmilk with plain water, since breastmilk gives your baby both hydration and the nutrition they need. If you are trying to understand what may be behind your baby’s loose stools, see our guide to the causes of baby diarrhea.
Formula Feeding During Diarrhea
When a formula fed baby has diarrhea, it can be tempting to add more water to the bottle. It may seem gentler on a sensitive tummy, but formula should still be prepared at full strength according to the package directions.
Diluting formula means your baby gets fewer calories and can upset the balance of fluids and minerals their body needs. Instead of changing the formula, try changing how often you offer it.
If a full bottle feels like too much, offer smaller amounts more often. For example, you can try 1 to 2 oz every 30 to 45 minutes instead of a larger bottle all at once. This may be easier for a tummy that is feeling unsettled.
If your baby has ongoing bloating or seems to have trouble with regular formula after diarrhea, talk with your pediatrician before making a switch. A temporary lactose free formula may sometimes be recommended while the gut recovers.
Solid Foods for Babies Over 6 Months
If your baby is over 6 months and already eating solids, there is usually no need to put meals on hold. Keep offering familiar, nourishing foods along with plenty of fluids.
Soft foods such as oatmeal, mashed potatoes, and bananas can be easy choices when your baby’s tummy is unsettled. Offer small portions and let your baby decide how much they want.
Some babies have less appetite during diarrhea. That is okay. Do not force solids if your baby turns away from food. Fluids are more important while your baby is having frequent loose stools.
Once your baby starts feeling better, you can gradually return to their usual meals and feeding routine.
Keeping Your Baby Hydrated During Diarrhea
How to Give Oral Rehydration Solution
When your baby has frequent loose stools, keeping them hydrated becomes one of the most important things you can do. Oral rehydration solutions (ORS) such as Pedialyte and Oresol contain a careful balance of fluids and electrolytes to help replace what your baby loses through diarrhea.
Offer 1 to 2 teaspoons (5 to 10 ml) every 5 minutes. Small amounts are often easier for a baby with an upset tummy to handle than a large bottle at once.
Plain water is not the best choice during significant diarrhea because it does not replace the salts your baby loses. ORS helps replace both fluids and electrolytes while your baby recovers.
If your baby does not want to drink from a bottle, do not force a full feed. A clean oral syringe can help you give 5 to 10 ml at a time, slowly into the inside of the cheek. Keep offering small amounts every few minutes.
The goal is not to make your baby drink a lot at once. Small, frequent amounts can be easier to manage, especially when your baby feels sick.
Medicines to Avoid During Diarrhea
It can be tempting to look for medicine that will stop the diarrhea quickly. For babies and young children, however, over the counter anti diarrhea medicines should not be given unless a pediatrician specifically recommends them.
These medicines are not a routine treatment for infant diarrhea and may cause serious side effects.
For now, focus on fluids, regular feeding, and gentle skin care. If you are unsure about a medicine, speak with your pediatrician before giving it. You can also read our guide to baby diarrhea medicine and treatment.
Call your pediatrician if your baby cannot keep fluids down for more than 4 hours, becomes increasingly sleepy or difficult to wake, or you are worried about dehydration.
Foods to Avoid During Diarrhea
Do Babies Need the BRAT Diet?
The BRAT diet once seemed like the go to answer for diarrhea. It focused on bananas, rice, applesauce, and toast. Today, that approach is considered too restrictive for babies.
Your baby still needs a variety of nutrients while recovering. Healthy fats, protein, and other nutrients help support the body as it heals. So instead of limiting meals to a few plain foods, continue offering age appropriate, nourishing foods along with regular fluids.
There is also no need to make your baby eat more than they want. Some babies naturally eat less when they are not feeling well. Keep offering food without forcing it, and let your baby decide how much they can manage.
If teething or diarrhea means more drooling, a soft absorbent bamboo bandana bib can also help keep your baby's neck area more comfortable while they recover.
Foods and Drinks to Avoid
Some foods and drinks can make diarrhea harder to manage. Skip sugary drinks and fruit juices such as apple juice, grape juice, sweetened tea, and soda. Their high sugar content can draw more water into the intestines and may make loose stools worse.
It is also best to avoid greasy, fried, and heavily processed foods while your baby is recovering. These foods can be harder on an already unsettled tummy.
Instead, keep meals simple and familiar. Plain, baked, or steamed foods and lean proteins are gentler choices. Once your baby's appetite and stools return to normal, you can gradually return to their usual meals.
Signs of Dehydration and Diaper Care
When to Get Help for Dehydration
Diarrhea can cause babies to lose fluids quickly, so it is important to keep an eye on wet diapers and how your baby is acting.
Contact your pediatrician or seek urgent medical care if your baby has no wet diaper for 6 hours, has a high fever, or you notice blood or thick mucus in the stool. Babies under 6 months old with diarrhea also need prompt medical advice.
Watch for other signs that your baby may need help. These include very little urine, crying without tears, unusual sleepiness, or a sunken soft spot.
If your baby has no wet diaper for 6 hours, do not wait for more obvious signs of dehydration. Call your pediatrician or seek urgent care. If your baby is difficult to wake, has blood in the diaper, or seems very unwell, seek medical care right away.
Protecting Your Baby's Skin During Diarrhea
Frequent loose stools can be tough on a baby's sensitive skin. After several messy diapers, the diaper area can quickly become red, sore, and irritated.
A simple barrier can make a big difference. Apply a generous layer of zinc oxide or petroleum based diaper cream during diaper changes. This helps protect the skin from moisture and frequent contact with stool.
For more tips on managing baby diarrhea, remember that skin care matters too. Keeping your baby's skin comfortable can make an already difficult few days a little easier.
Frequent nighttime changes can be tiring for both you and your baby. Easy change clothing can help make those moments less stressful. Bamboo baby bodysuits can be rolled down during a messy diaper change. This helps avoid pulling a soiled bodysuit over your baby's head and makes cleanup a little easier.
Supporting Your Baby Through Diarrhea Recovery
When your baby has diarrhea, the days can feel long and tiring, with frequent feedings and diaper changes that may leave you feeling unsure. The reassuring part is that feeding a baby with diarrhea does not need to be complicated—consistent, simple care is usually enough.
Continue breastfeeding as normal. If your baby uses formula, keep it undiluted. You can also give oral rehydration solution in small, regular sips when needed. For babies already on solids, stick with familiar foods and let them eat at their own pace.
Skin irritation is also common during this time, so gentle cleaning and protection can help keep your baby more comfortable. Soft, breathable clothing and absorbent accessories can also make repeated changes easier for both you and your baby.
There is no need for a complicated plan just steady hydration, appropriate feeding, and gentle care as your baby recovers.
