Symptoms - Newborn jaundice

Jaundice usually appears about 3 days after birth and disappears by the time the baby is 2 weeks old.

In premature babies, who are more prone to jaundice, it can take 5 to 7 days to appear and usually lasts about 3 weeks.

It also tends to last longer in babies who are breastfed, affecting some babies for a few months.

If your baby has jaundice, their skin will look slightly yellow. The yellowing of the skin usually starts on the head and face, before spreading to the chest and stomach.

In some babies, the yellowing reaches their arms and legs. The yellowing may also increase if you press an area of skin down with your finger.

Changes in skin colour can be more difficult to spot if your baby has a darker skin tone.

In these cases, yellowing may be more obvious elsewhere, such as:

  • in the whites of their eyes
  • inside their mouth
  • on the soles of their feet
  • on the palms of their hands

A newborn baby with jaundice may also:

  • be sleepy
  • not want to feed or not feed as well as usual
  • have dark, yellow pee (it should be colourless)
  • have pale poo (it should be yellow or orange)

When to get medical advice

Your baby will usually be examined for signs of jaundice within 72 hours of being born, as part of the newborn physical examination.

If your baby develops any signs of jaundice after this time, speak to your midwife, health visitor or GP as soon as possible for advice.

In most cases, jaundice is harmless and isn't a sign of an underlying condition.

It usually clears up on its own by the time a baby is 2 weeks old.

While jaundice isn't usually a cause for concern, it's important to determine whether your baby needs treatment.
