Tabela de Cores de Cocô de Bebê - O Que é Normal?

Infant stool changes colour and texture dramatically over the first weeks, and almost all of that variation is normal. The useful thing a chart can do is separate the wide band of normal from the three colours that genuinely matter: white or chalky, red with blood, and black after the newborn period. Everything from yellow through green to brown is generally unremarkable in a thriving baby.

What is normal at each stage

The first stools are meconium, a sticky dark green-black material made of everything swallowed in utero. It gives way over the first few days to transitional stool, then to a pattern that depends mainly on whether the baby is breastfed or formula fed. Introducing solids changes it again, and undigested food appearing in the nappy at that stage is expected rather than concerning.

• A breastfed baby who is gaining weight can go several days, occasionally up to a week, without a stool. That is normal provided the stool is soft when it comes.
• Straining, grunting and going red in the face while passing a soft stool is normal infant behaviour and is not constipation.

The three colours that need attention

White, chalky or pale grey stool suggests bile is not reaching the intestine. In a young infant the concern is biliary atresia, where surgical outcomes depend strongly on how early it is treated, so pale stool in a jaundiced infant is a same-day medical problem rather than something to watch.

Red streaks or visible blood need assessment. In a breastfed newborn a small amount can come from a cracked maternal nipple and is harmless, but blood can also indicate an anal fissure, a cow milk protein allergy, or less commonly an obstruction. Black stool after meconium has cleared suggests digested blood from higher in the gut and needs urgent review.

• Pale, chalky or white stool: seek medical review the same day, particularly if the baby is also jaundiced.
• Blood in the stool, or black stool after the first week: seek medical review.
• Currant-jelly stool with episodes of drawing the legs up and inconsolable crying is a classic description of intussusception and is an emergency.

Constipation and diarrhoea in infants

Constipation in infancy is judged by the consistency of the stool and the effort of passing it, not by how often it happens. Hard pellets that are painful to pass indicate constipation even at daily frequency; a soft stool every fifth day in a thriving breastfed baby does not. Constipation is uncommon in exclusively breastfed infants and becomes more likely after formula or solids are introduced.

Diarrhoea in an infant is a change: stools that become suddenly more frequent, much more watery, and larger in volume. The clinical concern is dehydration rather than the stool itself, so the things to watch are wet nappies, alertness, and whether the baby is feeding. Fewer wet nappies, a sunken fontanelle, unusual lethargy or no tears when crying all warrant prompt assessment.

Limitações

• This chart describes typical patterns. It cannot diagnose anything, and a baby who seems unwell needs assessment regardless of what the nappy looks like.
• Colour perception varies with nappy material and lighting. If you are unsure whether a stool is pale enough to worry about, photograph it in daylight and show a clinician.
• Iron supplements and some foods change stool colour harmlessly. Iron commonly darkens stool, and beetroot can make it look red.
• Frequency norms differ so widely between healthy infants that frequency alone is a poor indicator. Weight gain, feeding and general behaviour carry far more information.
• Premature infants and those with known gastrointestinal conditions follow different patterns and should be assessed against advice specific to them.
• Nothing here substitutes for in-person assessment. Pale, bloody or black stool needs a clinician, not a chart.

Perguntas frequentes

What colour should baby poop be?

Anything from mustard yellow through green to brown is normal. The colours that need medical attention are white or chalky pale, red with blood, and black once meconium has cleared.

Is green baby poop a problem?

Usually not. Green stool is common in both breastfed and formula-fed babies and is generally unremarkable in a baby who is feeding and gaining weight normally. It is not by itself a sign of a feeding problem.

How often should a newborn poop?

Frequency varies enormously. Breastfed newborns often go after most feeds, then may slow to once every few days, occasionally up to a week, which is normal if the stool stays soft. Formula-fed babies typically go one to four times a day.

What does white or pale baby poop mean?

It suggests bile is not reaching the intestine, which in an infant raises concern for biliary atresia. Because outcomes depend on early treatment, pale or chalky stool warrants same-day medical review, especially if the baby is jaundiced.

How do I know if my baby is constipated?

By the stool consistency and the effort, not the frequency. Hard, pellet-like stools that are painful to pass indicate constipation. Straining and grunting while passing a soft stool is normal infant behaviour.
