How to Treat Diarrhea and Dehydration in Infants and Children

My son came down with a severe case of diarrhea when he was one year old. It lasted for three days and we had to take him to the ER.

Dr. Heather Finlay-Morreale, Pediatrician, University of Massachusetts Memorial Medical Group


What to Do to Stop Infant Diarrhea

"Probiotics, whether in powder form or in foods with live cultures such as yogurt or kefir can help diarrhea," says Dr. Heather Finlay-Morreale, a pediatrician with University of Massachusetts Memorial Medical Group. "Babies should continue to nurse or take formula. Milk does not need to be stopped. Smaller, more frequent feeds may be helpful."

  • Continue nursing or offering formula
  • Smaller, more frequent feedings may help
  • For older children, offer probiotics in food or powder form.

When Should I Contact the Doctor About My Baby's Diarrhea?

According to Dr. Finlay-Morreale, reasons to call your doctor about diarrhea include:

  • Bloody diarrhea
  • Stool that is white, black, tarry, or red
  • Dehydration
  • Prolonged diarrhea
  • A large volume of stools per day
  • If there has been recent international travel or camping
  • Persistent vomiting
  • If your baby is under three months old.

Symptoms of Diarrhea in Infants

Diarrhea is characterized by the appearance of watery and loose stools more than three times in 24 hours. In most cases, diarrhea will go away on its own. However, it can lead to dehydration, which is a serious problem.

An infant's poop is already soft. Babies who are breasted typically have runnier poop than babies who are fed formula.

With that in mind, even an infant can get diarrhea. When this happens, the poop is even looser, more watery, and there may be more of it than a regular poopy diaper.

Applesauce (not sliced apples) can help treat diarrhea as apples have a binding effect on poop. Applesauce is also a hydrating food.

What Are the Symptoms of Dehydration in Infants and Children?

The biggest concern when it comes to diarrhea is dehydration. The body loses more water when the poops are more watery than usual, so it's important to look for signs of dehydration.

Keep an eye out for:

  • weight loss
  • dry or sticky mouth
  • lack of tears
  • fast heartbeat
  • poor skin turgor (when the skin on the back of the hand stays elevated after it is pulled up and released)
  • sunken eyes
  • lethargy
  • limpness
  • decreased number of wet diapers
Toddlers and older children can eat toast when recovering from diarrhea.

Foods to Treat Diarrhea or Dehydration in a Baby

If your child is eating solid foods and can keep food down, continue to feed them normal foods (avoiding some of the items below). Doctors no longer recommend limiting food to the BRAT diet (bananas, rice, applesauce, and toast).

The following diet plan can help your baby recover.

  1. Strict oral rehydration solution like Pedialyte every 4-6 hours. This is the most important step. Do not let your baby dehydrate. Continue breastfeeding or giving formula. Watch carefully how the baby reacts to milk and decide whether to temporarily stop feeding milk. Sometimes nothing can stay in the stomach. If your baby refuses milk, try Pedialyte.
  2. Bland foods. If you have started giving solids to your baby, feed her applesauce, strained banana, saltines, strained carrots, strained squash, mashed potatoes(no additives), rice cereal and oatmeal. You can also feed her toast, crackers, breads, pretzels, rice, mashed potatoes (no additives), noodles (no additives), bananas, applesauce, carrots, squash, Rice Krispies, Cheerios, oatmeal, and yogurt with active cultures.
  3. Milk products. Some babies may become lactose intolerant during this time, so consult your pediatrician.
  4. No oils or butter.
  5. No spicy foods or sauces until diarrhea subsides.

Note: You should always consult with your child's doctor before starting any kind of medication or if you have any doubts.

Check out the video below for more information about how to detect dehydration.

Mashed bananas can help resolve diarrhea. Bananas have a binding effect on poop and can help settle the stomach as well.

When a Baby Needs Hospitalization to Treat Diarrhea

When he was one year old, our son got a severe case of diarrhea that lasted for three days. We ended up going to the emergency room because he became completely dehydrated. He completely recovered after the doctors gave him intravenous fluids, but we were in the hospital for two days.

It was heartbreaking to watch the nurses search for a vein to insert the IV. It is very hard to find a vein when the person is dehydrated. We learned a lot from that experience and I wrote this article as a guide for parents so they know how to treat diarrhea in their own infants and children.

Rice cereal is a good food to offer your baby when they have diarrhea.

Possible Causes of Infant Diarrhea

  1. Teething
  2. Changes in the mother's diet, if the infant is breastfed.
  3. Infections such as norovirus (the flu).
  4. Rotavirus (preventable with a vaccine). This virus spreads easily through hand contact with germs.
  5. Bacterial infections from contaminated food and water. Common bacteria include Salmonella, Escherichia coli (E.coli), and Campylobacter.
  6. Inflammation such as inflammatory bowel disease.
  7. Celiac disease.
  8. Milk or other protein intolerance.
  9. Carbohydrate malabsorption (including lactose intolerance), or “toddler’s diarrhea” a chronic diarrhea where undigested food matter is seen in stool are all causes of diarrhea.
  10. Parasites such as Giardia lamblia, Cryptosporidium, and Entamoeba histolytica.
  11. Reaction to medicines: Antibiotics, blood pressure medications, antacids containing magnesium, and cancer drugs can cause infant diarrhea.
Toddlers and older children can eat saltine crackers when recovering from diarrhea.

How to Prevent Diarrhea

  1. The winter months are prime time for norovirus. Be careful to wash your hands and your child's hands after being in public places and before eating. Hand sanitizer does not kill norovirus so soap and water work best.
  2. Some diarrhea illnesses are spread by food, so careful washing of produce and thorough cooking of meat and eggs is advised.
  3. Hygiene is key to prevent one member of the house from spreading diarrhea to the rest of the house. Hands should be washed with soap and warm water after handling dirty diapers or vomit.
  4. Use bleach wipes to clean bathrooms and changing tables.

How to Prevent Dehydration

Do Antibiotics Cause Diarrhea?

"Antibiotics cause diarrhea in a few ways," says Dr. Finlay-Morreale. "Amoxicillin-clavulanate causes diarrhea in many people due to the clavulanate portion. Others are thought to disrupt the gut flora and cause diarrhea. Finally, a certain bacteria, c. difficile, can overgrow following antibiotic use and cause severe diarrhea."

What Type of Anti-Diarrhea Medicine Will My Doctor Prescribe?

According to Dr. Finlay-Morreale, anti-diarrheal medication is typically not used in children. Both the two most common ones, bismuth salicylate and loperamide, are not advised for children.

Typically, antibiotics are only used if a bacterial infection is confirmed by stool culture. If there is vomiting as well as diarrhea, ondansetron can treat the vomiting but can make diarrhea worse.

EmmaD on July 07, 2014:

If your little one will not take the rehydration products because,lets face it, they taste nasty- then perhaps this tip from the pediatrician might help. Make up the rehydration product according to the instructions then FREEZE it in little pieces,perhaps an ice cube tray or lolly moulds. They are more likely to take more of it in and they don't realise its medicine. Good luck xx

my 14 month old daughter started with sickness early hours thursday morning, she started with dierreah thursday afternoon, she has seen a doctor on thursday that was concerned about her becoming de-hydrated, so i followed his advice and friday when she was no better i took her back to the doctors and they gave her some dioralyte to replace any lost salts n vitamins, will this keep her hydrated?? she is not herself, is not interested in playing and spends a lot of the day sleeping, throwing her self around as doesn't no what she wants or sat cuddling me! i don't want to go back to the docs n look silly if i don't need to-whats ur advice??

i have also stopped giving her milk all she is having is water.

-she has sore lips

-she is slapping her lips together(suggesting she is thirsty)

-poo is very very watery and yellow with a strong smell

-lots of trumps

-dark circles around both eyes

Jen on January 13, 2012:

When your baby is sick, you should allow them to breastfeed MORE not less. Human breast milk is not a dairy product. This article is very ill-informed, and sadly it seems that the doctors that got you confused with a cow were as well. If you want information on how to help your breastfed baby when they are ill go to

Hilton Dominguez on December 19, 2011:

im going crazy as a dad reading n trying to do the right thing. we have a 6 month old boy who got sick 4 days ago for his first time. i took him to the doctor plus ER already they say give it a few more days to allow the virus exit his system. fever is controlled now hovering around 99 to 100...was vomiting some yesterday but today is just diahhrea w every breast feed.....he is irritable n very fatigued...eyes scared he gets dehydrated so im starting to give more water now which he has a lot of interest in plus a little but of applesauce. mild productive cough...hoarsed vocals...i cant wait to c him get thru this already...ive consider stopping the breastmilk but not sure thas a great idea....anyhow thanks all of u for sharing ur exper n thoughts very calming hearing other cases....these stomach virus r something poor kid i hate seen him like this soo needy n winy without monitoring his temp n checkng for signs of dehyd......hopefully he can recover tmrrw cuz mommy needs to go to work n he just wants to b in her arms plus i can t breast feed lol.....

thank u soo much.. the best advice anyone could have given..

Erin on December 08, 2011:

Please use actual medical advice not this article. I don't imagine any doctor would suggest stopping breastfeeding during a bout of diarrhea. Nor is gastroenteritis the flu. Please don't state your opinion as fact. People please use common sense. My lo has had diarrhea for almost a week. Still nursing and feeding soy milk and most other regular diet. She's a happy little bug.

Declan's Mummy on December 08, 2011:

Hi 'needs advice'...did your sons diarrhea settle down? My nearly 12 week old son has had diarrhea for 4 weeks now. He got the rotavirus 2 days before he was due for the immunisation. the virus gave him shocking diarrhea, but it kept continuing so the paediatritian told me that he has most probably become temporary lactose intolorent because it stripped the lining and good bacteria from his gut, so I am on a strict no lactose diet (breastfeeding) to fix the problem, but that has been 10 days now, and while he doesn't seem in pain anymore, he still has diarrhea! Im off to the doctors next week but need advice too!!!

bettermom on December 05, 2011:

Ryan's mommy on October 07, 2011:

If you are going to keep Breastfeeding when your child has diarrhea, which I think is great, then you need to ensure that you eliminate all dairy from your diet. It is also very important to keep an eye out for any foods that you may be consuming that can be affecting your child. A breastfeeding mom, when their child has diarrhea, will want to be on a bland foods diet to rule out any food intolerance/allergy their baby may have developed until the child is fine again.
