Baby Poop Texture Guide: Seedy, Pasty, Watery, or Hard?

There is no single “right” baby poop texture. A baby’s age, whether they receive breast milk or formula, and whether they have started solids all influence what you see in the diaper. The most useful comparison is often with your own baby’s usual pattern.

Seedy or loose stool

Breastfed newborns often have yellow, loose stools with small seed-like particles. Loose stool by itself is not the same as diarrhea in a young infant.

Pasty or peanut-butter-like stool

Formula-fed babies often have stools that are thicker than breastfed babies’ stools, commonly tan or yellow. After solids begin, stools may gradually become more formed and may reflect foods recently eaten.

Very watery stool

Diarrhea is usually a noticeable change from your baby’s normal pattern: stools may be much more watery, more frequent, or both. Pay particular attention to wet diapers, feeding, alertness, vomiting, fever, and whether there is blood.

Hard, dry, or pellet-like stool

Constipation is about stool that is hard, dry, and difficult or painful to pass—not simply going several days without pooping. Straining, grunting, or a red face can be normal when stool remains soft.

What to record

When to call a clinician

Contact your baby’s clinician if stools are persistently very watery, hard with blood, or accompanied by poor feeding, fever, repeated vomiting, fewer wet diapers, or a baby who seems unusually sleepy or unwell.
