White or Very Pale Gray
Very pale stool (sometimes described as "chalk-like") may indicate a
lack of bile in the digestive system.
⚠️ This situation requires immediate medical evaluation.
Stool color can change because of food, medications, or a small virus — and in most cases it is completely normal.
Many parents ask: “My child’s stool is green — is that normal?” or “A dark color suddenly appeared — is it dangerous?”
Dear parents, we know that the color of a diaper can sometimes be surprising and even stressful.
That’s why we created a smart and quick tool to help you understand what different stool colors may mean, reduce unnecessary worry, and know when it may be time to seek medical advice.
In most cases, there is no need to worry — but there are some situations that do require medical attention.

White or Very Pale Gray
Very pale stool (sometimes described as "chalk-like") may indicate a
lack of bile in the digestive system.
⚠️ This situation requires immediate medical evaluation.
Black (Tar-like)
In babies older than one week, thick black stool that looks like tar may indicate bleeding in the upper digestive tract.
Red
This color may indicate the presence of blood in the stool.
This tool was developed by KidGil, with guidance from a certified pediatric dietitian, based on clinical experience and daily work with parents and infants.
It is designed to help parents understand when a stool color may be within the expected range and when it may be a good idea to seek medical advice. It does not replace a medical evaluation.
In most cases, green stool in a baby or child is not a medical problem. Green stool can appear because of food (such as green vegetables), iron supplements, a mild virus, or faster movement of stool through the intestines.
If your child feels well, is eating and drinking normally, and has no other concerning symptoms, there is usually no reason to worry.
It is a good idea to seek medical advice if green stool is accompanied by high fever, prolonged diarrhea, severe abdominal pain, or signs of dehydration.
Not always. Red stool in a baby or child may be caused by foods such as beets, tomatoes, or food coloring.
However, red stool can also indicate blood in the stool — for example, from a small anal fissure caused by constipation.
If red stool happens repeatedly, looks like fresh blood, or is accompanied by pain, fever, or severe diarrhea, it is recommended to seek medical advice.
In general, normal stool colors may range between brown, yellow, mustard, and green.
In breastfed babies, stool is often yellow or mustard-colored, while in formula-fed babies it is usually light brown to greenish.
Changes in stool color are very common after dietary changes, and this is usually normal if the child feels well overall.
It is worth seeking medical evaluation if any of the following appears:
White or pale gray stool
Black stool (that is not meconium)
Clear blood in the stool
A color change that comes with high fever, severe abdominal pain, repeated vomiting, or unusual lethargy
If you feel that something is simply “not normal”, it is always reasonable to ask for medical advice.
Growth tracking, charts for babies and preterm infants, BMI, readiness for solid foods, baby stool color checks, and more — all in one place to help you quickly understand your child’s development with confidence.
