Red Streaks in Baby Poop: What Should Parents Do?

Updated Jul 29, 20266 minRed Poop • Safety • When to Call Doctor

Key takeaway

Foods and other factors can make stool look red, but any suspected blood in a baby’s stool should be brought to the attention of their clinician.

Seeing red in a diaper can feel alarming. Red coloring is not always blood: depending on age and diet, food, medicine, or other material may change how stool looks. But because it can be difficult to tell visually, it is safest not to assume.

First, note what you see

Is the red color mixed through the stool, a streak on the outside, or only on the diaper?
Has your baby eaten a red-colored food, or is there a medicine or supplement that could change stool color?
Is your baby feeding normally and acting like themselves?

Why a photo is not enough

Lighting, diaper material, food pigments, and image quality can make colors appear different. An AI observation or photo log can help you describe what you saw, but it cannot confirm whether a red substance is blood or identify its cause.

Contact your baby’s clinician

The American Academy of Pediatrics advises parents to bring any amount of bloody poop to a pediatrician’s attention. Seek urgent care right away if your baby looks very ill, is unusually sleepy, is feeding poorly, has repeated vomiting, or you are worried about their condition.

What to bring or record

A photo taken in good light, if appropriate
The diaper or a sample only if your clinician asks you to save one
The time it happened and any recent food, formula, or medicine changes
Other symptoms, including fever, diarrhea, constipation, vomiting, or reduced wet diapers
