My baby is yellow / jaundice

Jaundice is the name given to yellowing of the skin and the whites of the eyes. Jaundice in newborn babies is very common, is usually harmless and usually clears up on its own after 10–14 days.

It is more common in premature babies were born before 37 weeks.  Jaundice usually develops by 2-3 days after birth. If your baby looks yellow, health professionals may do ‘blood tests’ to check the level of jaundice.

Why do babies get jaundice?

It is completely normal for babies to get mildly jaundiced. That's because babies are born with high levels of red cells in their blood. After birth, as these red cells break down, they produce a yellow pigment called bilirubin. Bilirubin is normally removed by the liver, but as babies have an immature liver at birth, it can take up to 2 weeks for the bilirubin to clear. Breast feeding can cause mild jaundice as well - however the benefits of breastfeeding far outweigh the mild jaundice that may results.

In a small number of cases, there may be an underlying reason for a baby becoming severely jaundiced. This includes blood group incompatibility between the mother and baby, higher than normal level of red cells in the baby or genetic problems with the red cells. If there is a family history of red cell problems, please let your midwife know during pregnancy - your baby may need special tests after birth.

Jaundice occasionally persists beyond two weeks of age (beyond three weeks for babies born preterm - less than 37 completed weeks). If this happens, your baby is likely to be called into the hospital for further blood tests to find out reasons for the prolongation. In most instances, the cause for this is just your baby's liver taking a little longer to adapt (physiological jaundice) or breast milk jaundice. Neither of these are a problem for your baby. We also check the baby for much rarer causes of prolonged jaundice. In most instances, the jaundice settles without any treatment.

How will my baby get checked for jaundice?

All newborn babies get a full head to toe examination within 72 hours of being born. Sometimes jaundice is picked up during this examination. If your baby develops jaundice at home you can speak to your midwife. If your baby falls within 'Amber', see a healthcare professional such as a midwife urgently as a blood test may be needed to check their jaundice 'level'. If your baby has any 'Red' features, they will need to be immediately assessed in hospital - dial 999 and ask for assistance from the emergency services.

Feeding your baby during jaundice:

Continue to feed your baby as planned. If you are breastfeeding your baby, continue to breast feed regularly and wake up your baby for feeds, if necessary. Formula supplementation, if not by choice, should only be considered if recommended by medical professionals.

Treatment of neonatal jaundice:

In a vast majority of babies, jaundice does not need treatment and should resolve completely by two weeks of age. Treatment is needed only if the baby's jaundice 'level' is high and likely to rise further without treatment. This decision will be made by a healthcare professional after they have checked the baby's jaundice 'level' using a hand-held device, or a blood test if needed.

The most common form of treatment is phototherapy (light treatment). Your hospital will explain what this means for your baby.
