It is likely at this time that you will develop an unprecedented interest in poo – at least your baby's! This is because the content of your baby's nappy gives important clues to its health.
Green or yellow poo
Your baby's first bowel movement is important and should happen within 24 hours after the birth. A newborn infant's first stool is known as meconium and is greenish black. Meconium is very sticky and hard to wash out. Try using a little baby oil. A baby's faeces typically look like this for the first few days.
If you are breastfeeding, the faeces will gradually become thin and yellowish green with a slightly sour smell. A little later, it will gain a mustard-like colour and consistency. This type of poo usually does not have much odour.
Initially, the baby's stool is often thin and comes out quite explosively. This is completely normal, so don't worry that your baby has diarrhoea.
Bottle fed babies have darker faeces
At 2 to 3 months old, your baby will poop less often and the smell will change.
Babies fed with infant formula usually have slightly firmer and darker faeces with a stronger smell. They are a little more likely to be constipated. If this happens, it might help to change to a different formula. Consult your paediatric centre for advice.
Breastfed babies almost never get constipated.
Green faeces are completely normal if the baby is otherwise healthy. However, if your baby's faeces are white or greyish white, it could mean that the bile, which is what normally gives faeces their colour, is not reaching the intestines. This can be a symptom of problems with the liver or bile ducts. If the poo doesn't soon regain its normal colour, consult a paediatrician.
