Normal Baby Poo: Colour, Texture & Frequency Guide | Parenting Hub

A plain-English guide to what baby poo should look like — from newborn mustard seedy to toddler formed — and which colours are red flags.

Baby poo changes a lot in the first year. Most colours and textures are normal — only three (white, red, and black after meconium) are real red flags.

Normal colours

  • Mustard yellow, seedy — typical breastfed
  • Tan or pale brown, pasty — typical formula-fed
  • Green — common and usually normal (fast transit, iron in formula, lots of veg)
  • Brown — once on solids
  • Orange, red flecks (from beetroot/tomato), blue (blueberries) — diet-related, fine

Red-flag colours

  • White, pale grey or chalky — see GP today (possible liver issue)
  • Red blood mixed through or large amounts — GP today
  • Black (after meconium has cleared) — GP today (possible upper-gut bleeding)

Texture by age

  • Newborn breastfed: runny, seedy, almost yoghurt-like
  • Newborn formula: thicker, peanut-butter consistency
  • Solids started: thicker, browner, more smell
  • Toddler: formed sausage shape

Frequency

Newborn breastfed: many a day in the first weeks, then can drop to once every 5–10 days after 6 weeks (still normal if soft). Formula-fed: usually at least once a day. Once on solids: most settle to 1–3 per day.

When to seek help

  • White, chalky or pale poo at any age
  • Red blood (not a streak from a tiny fissure) or black tarry poo
  • Hard, painful pellets with crying
  • No poo + vomiting + swollen tummy

Common questions

Should I worry about green poo?

Usually no — see our dedicated green poo article. It's almost always a normal variant.

How will I know my baby is constipated?

It's about consistency, not frequency — hard pellet-like poos and pain when passing them. See our constipation article.
