Baby poo colour chart

There is a variety of colours and textures when it comes to baby poo. It will depend on their age, whether they are breastfed or formula fed, and if they have started on solids.

What is normal?

Green / black (sticky tar-like)

This is normal for your baby’s first poo. It’s called ‘meconium’ and will change in the first couple of days.

Mustard yellow

For a breastfed baby, this is normal. It will be loose and a bit runny.

Darker yellow

Formula fed babies tend to have darker and slightly firmer poo.

Frothy green

Can happen with babies breastfed from both breasts frequently. Try feeding until one breast is drained before switching.

Dark green

Sometimes found with babies on formula. Usually because of the iron found in the formula and nothing to worry about.

Green / brown

As you start to introduce solid food, this will be one of the many shades you can expect to see in your baby’s nappy.

Orange

Another example of the variety of colours solid foods can produce in your baby’s poo.

Brown

As they get older, your baby’s poo will be more like grown-up poo.

What is not normal?

If you see any of the following types of poo in your baby’s nappy, see your doctor and take a sample or the nappy with you.

Red

Blood in your baby’s poo could be from constipation, if mum has cracked/bleeding nipples, or due to something more serious.

Chalk white

White or grey poo is not normal and could be a sign of a liver problem.

Black

Baby poo should only be green or black during the first few days; after that it could be a sign of something more serious.

Constipation versus diarrhoea

Constipation

Signs of constipation can include:

• a hard and dry poo
• a firm and pebble-like poo
• your baby being upset
• poo with a streak of blood

Diarrhoea

Signs of diarrhoea include:

• a watery poo
• more poo than usual
• baby is also unwell, particularly vomiting
• baby doesn't want to feed

If your baby is either constipated or has diarrhoea, visit your doctor or child health nurse.
