What color should baby poop be?

Normal baby poop ranges from mustard yellow (breastfed) to tan or light brown (formula-fed). Green is almost always normal too. The only colors that need same-day attention are white or chalky gray (possible liver issue) and black tarry stools after the first 3-4 days of life.

Is dark green baby poop normal?

Dark green poop is usually normal and often caused by iron-fortified formula, foremilk/hindmilk imbalance in breastfed babies, or green vegetables once solids start. If it's accompanied by mucus that persists more than 2 days, call your pediatrician.

What does white baby poop mean?

White, chalky, or very pale gray poop needs immediate medical attention. It can indicate a liver or bile duct problem that prevents bile from entering the digestive tract. Contact your pediatrician or go to urgent care the same day.

Should I be worried about red streaks in baby poop?

A small bright red streak on hard stool is usually a tiny anal fissure - a minor tear caused by constipation. It looks alarming but is rarely serious. Call your pediatrician the same day to discuss, especially if there's more than a small streak or if baby seems unwell.

Is orange baby poop normal?

Yes. Orange poop is almost always caused by foods like carrots, sweet potatoes, or squash once solids start. It's completely normal and nothing to worry about.

Baby Poop Color Chart: What Every Color Means (With Photos)

If you're reading this at 3am while staring at a diaper, you're not alone. Baby poop comes in a rainbow of colors, and most of them are completely normal. Here's your complete guide.

The Normal Colors

Mustard Yellow

This is the gold standard (pun intended) for breastfed babies. Mustard yellow, seedy poop is perfectly healthy and exactly what your pediatrician wants to see. The seeds are just undigested milk fat - totally normal.

Dark Yellow / Tan

Common in formula-fed babies. Formula produces slightly firmer, darker yellow to tan-colored stools. This is your baby's version of normal.

Green

Green poop is almost always normal. We cover all the causes in detail in Green Baby Poop: 7 Common Causes. It can happen from:

Foremilk/hindmilk imbalance in breastfed babies
Iron-fortified formula
Starting green vegetables (peas, spinach, avocado)
A mild stomach bug passing through

Unless it's accompanied by other symptoms, green poop is rarely a concern.

Orange

Usually caused by foods like carrots, sweet potatoes, or squash. Completely normal once baby starts solids.

The Watch Colors

Dark Green / Almost Black

In newborns, very dark green-black poop (meconium) is normal for the first few days. After that, very dark stools could indicate iron supplementation or digested blood. Worth mentioning at your next appointment.

Bright Green + Mucusy

If bright green poop comes with visible mucus strings, it might indicate a food sensitivity or mild infection. Monitor for a day or two, and call your pediatrician if it persists.

The Concern Colors

Red / Blood-Streaked

Small streaks of blood can come from tiny anal fissures (common with hard stools) or from cracked nipples if breastfeeding. Call your pediatrician the same day to discuss. For a full breakdown of every possible cause, see Blood in Your Baby's Diaper: A Calm Guide to Every Cause.

White / Chalky / Pale Gray

This is the one color that needs immediate attention. White or very pale stools can indicate a liver or bile duct problem. Contact your pediatrician right away.

Black (after newborn period)

After the meconium stage (first 3-4 days), black tarry stools can indicate digested blood. Contact your pediatrician promptly.

When to Call the Doctor

As a general rule, call your pediatrician if you see:

White, chalky, or very pale stools
Red blood (more than a small streak)
Black tarry stools after the newborn period
Any color change accompanied by fever, vomiting, or lethargy
Significant changes that last more than 2-3 days
