Stool seeds

Should there be curds in my baby’s poops?

Some babies have little white cheese-like clumps (seeds or curds) in their stools and others don’t; their presence or absence has no significance.

A) Describing stool curds

The normal stool of a one-week-old breastfed baby. It is yellow in colour and has small curds.

A baby’s stool can have curds that can be clumpy or seed-like. They consist of little white bits of cheesy material.

Some babies have seeds and some don’t. One study (Gustin 2018) showed that about one-third of exclusively breastfed babies had curds in their stool.

The presence or absence of seeds doesn’t mean anything. They are not caused by low amounts of fat in breast milk.
