Is it normal for my newborn baby’s poo to change colour?

The contents of your new baby's nappy can be strangely fascinating - but what's OK? And when is it worth seeing a doctor?

Isn’t it amazing how much you become interested in another human being’s poo when you become a mum? ?

And the sheer variety of colours and consistencies it comes in is amazing – and sometimes daunting, if it’s not quite what you were expecting.

Yep, poo is a big topic on our forum – and when you bring a new baby home it can all be a bit scary.

At the hospital, the doctors or midwives will probably make you aware of your baby’s first poo – meconium – which is often black and sticky.

After that though, it can go a range of colours – and consistencies – as mum debbiemc says (talking about breastfeed babies particular):

“Breastfed babies poos do come in some rather strange colours, green being one of them.

“Don’t worry –  you will have a rainbow of colourful nappies before long!”

And pixie_woo says:

“I was used to the mustard-yellow shade of baby poo and then one day I was greeted by lurid green!

“I have no idea what makes it change colour or texture (where do those lumps come from?)”

We spoke to GP Dr Philippa Kaye (also find her on Twitter), particularly about those early day poos, and she said this:

“The first few poos after birth look black/dark green and are very sticky and fairly stinky!

“This is called meconium and is entirely normal. Over the first few days it will turn green/yellow/brown: breast fed babies often have bright yellow ‘mustard seed’ like poo.

“It is also normal for babies to open their bowels anything from 8 times a day to twice a week!

“If after the meconium has passed your baby develops black stools, if it is white or if there is red blood in it seek medical advice.”
