Newborn poop: what’s normal

Meconium to yellow is the usual color story. Pale, clay-colored, or blood is a call. No diagnosis from this page.

We are not pediatricians. This is not medical advice. Your pediatrician knows this baby.

Poop is a diary, not a personality test. We will not diagnose allergy, infection, or “the wrong formula” from a photo. We will tell you the usual color story and the call colors.

The usual story

  • Meconium: dark, tarry, first days.
  • Then transitional stools.
  • Then, for many milk-fed babies, yellow (mustard, seedy if breastfed; pastier if formula). Your clinician told you what to expect.

Frequency varies. Some days are a lot. Some breastfed babies go less often after the first weeks — your pediatrician owns that sentence, not a chart we invent. Wet diapers and weight still live on enough milk.

Call (do not wait for a parenting group)

  • Pale, clay, or chalk-white stools
  • Blood that is more than a tiny streak you already asked about — or any amount that scares you
  • Black stools after meconium should have finished (ask; do not guess)
  • Poop plus fever 100.4°F under 3 months, plus a baby who will not wake, plus a swollen hard belly

Bring a photo to the first visit if you want. Bring the baby if the color is clay or the baby is sick.

What we will not do

  • Diagnose
  • Switch your formula from here
  • Tell you green always means “foremilk”
