What is meconium stool?

Meconium is your baby’s first poop. It is usually thick, sticky, and very dark green to black, which is why many parents search for black meconium stool in newborns. This newborn meconium stool is made up of materials your baby swallowed before birth, and it is a normal part of the first days of life.

What normal meconium stool usually looks like

Color

Normal meconium stool is often black or very dark green at first. This early color is expected in the first baby poop meconium stage.

Texture

Meconium poop in newborns is usually thick, sticky, and tar-like. It can be messy, but that texture is typical.

Timing

Most babies pass meconium within the first day after birth, and the stool then begins changing over the next few days as feeding increases.

When does meconium poop change?

Early transition

After the first black stools, many babies start having stools that look dark green or brownish as meconium begins to clear.

Feeding matters

As breast milk or formula intake increases, stool usually becomes less sticky and shifts away from the classic meconium stool color.

How long does meconium last

Meconium often lasts for the first couple of days, then transitions. If it has stayed black longer than expected, it can help to review your baby’s age, feeding, and stool pattern.

Reasons parents look more closely at meconium stool in newborns

It still looks black

Parents often want to know whether black meconium stool in a newborn is still normal or whether it should have changed by now.

The texture seems unusual

Because meconium is naturally sticky and thick, it can be hard to tell what is expected versus what seems off.

Baby seems to struggle

Some babies grunt or strain while passing stool. Looking at the full picture can help you understand whether this fits normal newborn behavior.

Why personalized guidance can help

Questions about newborn meconium stool are often about timing, color, and whether your baby’s pattern still fits normal meconium stool. A short assessment can help you sort through what you’re seeing and understand whether it sounds like a typical transition or something worth discussing with your pediatrician.
