The newborn phase is a time full of wonders, but also full of new challenges and worries. One of the issues that often causes concern for new parents is their baby's digestion. Diarrhea in particular can raise many questions: Is this normal? Should I see a doctor? What can I do?
What should you do if your newborn has diarrhea? For newborns with diarrhea, it's essential to ensure adequate hydration and to compensate for fluid loss. It is important to closely monitor your baby's condition and consult a pediatrician if diarrhea persists, signs of dehydration appear, or if there are any additional symptoms. Furthermore, maintaining hygiene and frequent diaper changes should be a priority to prevent skin issues.
In your baby's first months of life, you will learn that every “diaper report” tells its own story. In this article, we will explore together when exactly diarrhea in babies is considered to be present, how you can recognize it, and what the possible causes might be. You will also learn what to do if your baby has diarrhea and how Judes cloth diapers can help you manage this challenge in a clean and safe way.
Recognizing diarrhea in babies: a definition
As loving parents, you always want to make sure your child is well. That also means understanding what’s going on inside their little body. When it comes to diarrhea, it’s important to know exactly what it is so you can take appropriate action.
Diarrhea in newborns can primarily be recognized by a change in the stool's consistency and volume. If your baby fills the diaper more often than usual and the stool is more liquid than normal, this is considered diarrhea. For newborns who are still exclusively breastfed or formula-fed, having soft stool is normal. That’s why it can sometimes be difficult to distinguish diarrhea in very young babies.
So, it’s about an increase in stool frequency and a more watery consistency. Unlike what you might expect in adults, diarrhea in babies doesn’t necessarily mean a higher overall volume. It can also mean more frequent, smaller, and more liquid stools overall.
However, keep in mind that occasional changes in your baby’s bowel movements are normal and can have various causes. They are not always a reason to worry. Still, it’s good to keep a watchful eye so that you notice changes and can respond appropriately.

The significance of a baby's stool
Your baby can’t tell you how they feel, so it’s up to you to look for signs that could indicate diarrhea. This can be a bit of a challenge, as every baby is unique—and so is their poop. Don’t worry, there are some clues that can help.
Frequency and consistency of stool
Normally, newborns have bowel movements several times a day, and the consistency can vary from solid to liquid, especially if they are breastfed. What characterizes diarrhea is a significant increase in stool frequency and a watery consistency that differs from your baby’s usual pattern.
Color differences in stool
Stool color can also give you some clues. A healthy breastfed baby’s stool is usually mustard yellow, while formula can cause a slightly firmer, greenish-yellow to brownish stool. Diarrhea, on the other hand, may appear lighter, greenish, or even watery in color.
Here’s a small guide to baby stool:
Stool Color |
Consistency |
Possible Meaning |
Mustard yellow |
Soft/Mushy |
Normal for breastfed babies |
Greenish-yellow to brownish |
Mushy/Firm |
Normal for formula-fed babies |
Greenish/Watery |
Thin/Watery |
Diarrhea |
Orange/Red |
Varies |
Indication of food intolerance or other issues (seek medical advice) |
Very pale/Whitish |
Varies |
Possible sign of liver problems (seek medical advice) |
Black |
Tarry |
Normal after birth (meconium), seek medical advice afterward |
Note: This is a general guideline. Variations can be normal, but if deviations persist, please seek medical advice.
It’s important to understand that diarrhea isn’t just about diapers. Also look out for other symptoms like irritability, fever, or changes in your baby’s well-being. These could be additional signs that something is wrong.
Now that you know what diarrhea in babies can look like, let’s turn to the possible causes and find out what might be behind it.
Newborn with diarrhea: possible causes
If your newborn has diarrhea, it’s a sign that their body is reacting to something. There are various reasons why diarrhea may occur. Below you’ll find some of the most common causes, so you can respond appropriately.
- Infections: Viruses, bacteria, or parasites can cause diarrhea. Rotaviruses are one of the most common causes of gastrointestinal infections in young children.
- Food intolerances and allergies: Some babies can be sensitive to ingredients in formula. Cow's milk protein allergy is one of the more frequent intolerances.
- Antibiotics or other medications: Sometimes, medications given to your baby can cause diarrhea by disrupting the balance of the gut flora.
- Sudden dietary changes: An abrupt change in your baby's diet can also result in diarrhea. This applies to both the switch from breast milk to formula as well as the introduction of solid foods.
- Travel or environmental changes: Sometimes, stress factors such as travel or changes in the environment can upset your baby’s stomach.
Note that mild and occasional diarrhea can be normal and often resolves on its own. But if you find that the diarrhea persists, is accompanied by fever, vomiting, or your baby shows signs of dehydration (such as sunken eyes, a dry diaper for several hours, or dry skin), you should definitely seek medical advice.
During the times when your baby is affected by diarrhea, a reliable diaper is essential. Judes cloth diapers are designed to be dependable even during these challenging moments and to protect your baby’s sensitive skin.
What to do when babies have diarrhea? First aid and measures
When your baby shows signs of diarrhea, this can be worrying at first. But there are effective steps you can take to help your child and ease their discomfort.
- Hydration is key: The most important thing with diarrhea is to make sure your baby gets enough fluids. Due to increased fluid loss, there is a risk of dehydration.
For breastfed babies: Continue breastfeeding, as breast milk provides the necessary nutrients and fluids and can even help shorten the duration of illness.
For formula-fed babies: Keep offering formula and talk to your pediatrician about whether additional fluids such as electrolyte solutions are advisable.
- Observation and nutrition: Keep a close eye on the frequency and consistency of your baby’s stool. If your baby is already eating solids, it may help to temporarily stick to easily digestible foods such as rice porridge, bananas, or grated apple (the so-called BRAT diet).
- Don’t hesitate to visit a doctor: If you are unsure or if the diarrhea lasts several days, is accompanied by fever or vomiting, don’t hesitate to see a doctor. Especially in the case of signs of dehydration, immediate action should be taken.
- Intensify hygiene measures: With a newborn who has diarrhea, it is even more important to pay attention to hygiene. Change diapers frequently to prevent skin irritation and clean the diaper area gently but thoroughly.
- Trust in cloth diapers: During this challenging time, Judes cloth diapers can be a great support. They are designed to remain leak-proof even with diarrhea and are gentle on your baby’s skin at the same time.

- Skin friendly: By avoiding aggressive super absorbents and chemicals, Judes creates a skin-friendly environment that minimizes the risk of diaper dermatitis.
Earlier potty training

Less time required
- Time efficient: Judes reduce the overall workload for parents, as you spend less time shopping and managing waste. Fifteen minutes of washing per week contrasts with countless hours spent on shopping and trash disposal.
Cost savings

No leaks
