Baby Stool Colours (Poop Guide)
Your baby's stool colour tells you a lot about their health. Green, yellow, brown, orange — usually perfectly normal. But WHITE, RED, or BLACK stool (after the meconium phase) can indicate serious problems and must be evaluated by a doctor immediately.
Posibles Causas
- 1YELLOW (mustardy, seedy): Normal for breastfed babies — healthy breast milk stool
- 2BROWN/TAN: Normal for formula-fed babies and after starting solids
- 3GREEN: Often harmless — foremilk excess, solids (spinach, peas), fast gut transit, iron supplements
- 4ORANGE: Normal colour from carotenoid-rich foods (carrots, sweet potatoes)
- 5BLACK (after meconium): May indicate upper gastrointestinal bleeding → see doctor
Qué Puedes Hacer
- For normal colours (yellow, brown, green, orange): No treatment needed — observe
- For green stool: lactation consultant if foremilk-hindmilk imbalance suspected
- For WHITE/PALE stool: see paediatrician or go to A&E IMMEDIATELY
- For RED stool: see paediatrician — could be anal fissure (harmless) or allergy
- For BLACK stool (after meconium phase): see paediatrician — possible internal bleeding
¿Cuándo Consultar al Médico?
- WHITE or CLAY-COLOURED stool → EMERGENCY: suspicion of biliary atresia (bile ducts blocked)
- RED stool or blood streaks: Possible anal fissure, cow's milk protein allergy, or gut infection
- BLACK, tarry stool after meconium phase: Suspicion of upper gastrointestinal bleeding
- Very watery stool (more than 8-10x daily): Diarrhoea with dehydration risk
