What is your baby's diaper telling you?
One photo. Ten seconds. Mila reads color, consistency, hydration and red flags against pediatric guidance, and gives you a clear next step in plain language.
The moment you actually need this
It's 3 AM. The diaper looks weird.
Should you call?
You scroll forums. You compare to a search-engine image grid. You second-guess yourself. Poop Decoder gives you a structured read in 10 seconds — not a verdict, a clear “here's what this most likely is, and here's exactly what to do next.”
Three steps, sixty seconds
No app to install. Works in the browser. No account needed for your first two reads.
- Step 1
Take a photo
Good light, close enough to see texture. JPEG, PNG, WebP, HEIC, up to 6 MB. Your camera or library — Mila doesn't care which.
- Step 2
Add context
Baby age, feeding type, hours since last BM, any recent food changes, fever or vomiting flags. Optional but it sharpens the reading a lot.
- Step 3
Read Mila's note
Color + consistency + hydration + frequency, plus a 4-level safety triage with the concrete next step. Saved to your history if you're Premium.
Why we trust the read
The science behind it
Bristol Stool Chart
Mila grades consistency on the seven-point Bristol scale, adapted for infants — so the same scale a pediatric GI uses in clinic is what scores your baby's seedy mush, soft formed or hard pellets.
AAP red-flag list
The four colors pediatricians treat as “call us today” — white / clay-pale, jet-black tarry past the newborn window, bright red blood, and grey-pale — sit at the top of the triage hierarchy and surface as an explicit safety flag.
Diet-aware reasoning
What's “normal” depends entirely on whether your baby is breastfed, formula-fed, mixed or on solids. Mila weighs your declared feed type as a strong prior — green stool in a 6-week breastfed baby reads very differently than the same green in a 9-month-old on solids.
Two-pass classifier
A cheap Haiku gate rejects blurry / dark / wiped-clean / off-topic photos before they reach the full Sonnet vision pass — saving you a vague reading and saving us the GPU. Quality score 5+ is the threshold to classify.
12 colors Mila knows
The color reference
Three groups: normal-for-some-diets (green tags), watch-context (no tag), red flags (red tags). Mila tells you which one applies to your baby's photo + diet.
Yellow seedy
Classic breastfed. Normal.
Often normalMustard
Breastfed + early formula. Normal.
Often normalTan / brown
Formula and early solids. Normal.
Often normalDark brown
On solids. Iron can darken. Normal.
Often normalGreen
Foremilk shift, iron, mild bug. Often normal.
Often normalOlive green
Watch alongside other signs.
Context-dependentMeconium black
Normal in the first 48h ONLY.
Context-dependentTarry black
Red flag past first week. Call doctor.
Red flagRed / blood
Red flag. Call your pediatrician.
Red flagWhite / clay
Urgent red flag. Call today.
Red flagGrey pale
Concerning. Pediatric assessment.

Eight consistency reads
Each consistency maps to a Bristol equivalent AND a hydration signal — so we tell you whether to think about dehydration, constipation, or carry on.
Liquid / watery
Bristol 7
↓ watch dehydration
Seedy & loose
Bristol 6
→ normal
Mushy / pasty
Bristol 5
→ normal
Soft formed
Bristol 4
→ normal
Firm formed
Bristol 3
→ normal
Lumpy
Bristol 2
↑ watch constipation
Hard pellets
Bristol 1
↑ watch constipation
Mucus strings

The triage hierarchy
Four safety levels — each with a clear action
Mila never just says “there's an issue”. She tells you which level you're at and exactly what to do in the next hour.
Looks healthy
Color and consistency fit your declared diet, no red flags. Carry on — keep an eye on hydration and feeding rhythm.
Worth watching
Borderline observation (mild constipation signal, slight green tint, frequency drift). Watch over 24-72h, hydrate well.
Call pediatrician today
Visible red flag (blood streaks, persistent mucus, unusual color). Get a same-day call with your pediatrician.
Seek urgent care
Severe red flag (jet-black tarry past newborn, white/clay-pale, bright blood + distress). Call urgent care or ER.
What it actually looks like
Three real questions, three real answers
“3-month-old, exclusively breastfed, stool is bright green and frothy.”
Mila's read
Likely a foremilk-hindmilk imbalance, not infection. Watch hydration, try fuller feeds on one side before switching. None safety level. Call if it lasts beyond 48h or baby is unsettled.
“7-month-old on solids, hard pellets, no BM for 4 days, very fussy.”
Mila's read
Constipation pattern. Increase fluid, offer pear / prune purée, warm bath + tummy massage. Watch level. If no BM in 24-48h despite hydration, or pain when passing, call pediatrician.
“6-week-old, breastfed, small red streaks visible in mostly-normal stool.”
Mila's read
Visible blood at any age is a red flag. Could be a small anal fissure, an allergy (cow milk protein), or infection. Urgent: call your pediatrician today and bring the photo.

What Poop Decoder is NOT
- Not a medical device. Not approved by any regulatory body. We give triage hints, not verdicts.
- Not a replacement for your pediatrician. Especially when a red flag is detected — call them. We'll tell you when.
- Not for adults, pets or lab analysis. The taxonomy is calibrated for infants 0-36 months.
- Not a guarantee. AI vision can misread (bad lighting, partial occlusion, ambiguous colors). When in doubt, retake the photo or escalate.
