My baby is yellow / jaundice
Jaundice is very common and affects about 6 out of 10 babies. It makes the skin and eyes look yellow. It happens more often in babies born before 37 weeks. Jaundice usually starts 2 to 3 days after birth and goes away by two weeks of age. Most of the time, it is not harmful.
Your newborn should be checked for jaundice at every opportunity, especially in the first 72 hours. This involves looking at your baby in bright light (natural light if possible) to see if they look yellow.
If your baby seems to have jaundice, your midwife should check the bilirubin level at their next routine check. If jaundice appears within the first 24 hours of life, your baby should be checked the same day—contact your midwife right away.

When should you worry?
If your child has any of the following:
- Unable to wake (unrousable)
- Rhythmic jerky movements of arms or legs (a seizure)
- Pauses in breathing or irregular breathing pattern
- Pale, mottled and feels abnormally cold to touch
- Is under 3 months of age with a temperature of 38°C / 100.4°F or above (unless fever in the 48 hours following vaccinations and no other red or amber features)
You need urgent help
Go to the nearest Hospital Emergency (A&E) Department or phone 999
If your child has any of the following:
- Jaundice appears in the first 24 hours of life
- Rapid progression in the intensity of 'yellowness'
- Looks very pale and yellow
- Becoming increasingly sleepy and less interested in feeding
- Unable to settle (inconsolable)
- No wet nappies in the last 8 hours
- Extremely pale (chalk coloured) stool - keep a sample to show the doctor
- Jaundice remaining beyond 2 weeks of life (after 3 weeks of life in a premature baby)
- Is 3-6 months of age with a temperature of 39°C / 102.2°F or above (but fever is common in babies up to 2 days after they receive vaccinations)
- Continues to have a fever of 38.0°C / 100.4°F or more for more than 5 days
You need to contact a doctor or midwife today
Please ring your GP surgery or call NHS 111 - dial 111
If your baby develops jaundice within the 24 hours of life, they should be seen by your midwife today to be reviewed and have their jaundice checked.
If symptoms persist for 4 hours or more and you have not been able to speak to either a member of staff from your GP practice or to NHS 111 staff, recheck that your child has not developed any red features.
Your baby has had their jaundice recently assessed by a health professional AND
- Continues to feed well, breast or formula. Has plenty of wet nappies and continues to pass green poo on day 2-3 changing to yellow "seedy" by day 5. Breast fed babies poo can appear "seedy" which are fat deposits within their poo and are a reassuring sign your baby is being well fed.
- Baby wakes up/cries regularly for feeds.
Additional information is available about infant crying and how to cope – click here.
Self care
Continue providing your child’s care at home. If you are still concerned about your child contact your Health Visitor or call NHS 111 – dial 111

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 (polycythaemia) 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 including urine infections, congenital viral infections (CMV), metabolic conditions (G6PD) and biliary atresia. Fortunately, these conditions are very rare and 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. In some instances, jaundice is picked up during this examination. If your baby develops jaundice at home, in most situations, they will not need to see a healthcare professional unless they have any red or amber features (see above). If your baby falls within 'Amber', see a GP or Community 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' either with a blood test or by using a hand-held device (which, if high, needs to be confirmed by a blood test).
The most common form of treatment is phototherapy. This is where a baby is kept exposed under special light in the hospital. This light alters the pigment bilirubin and makes it easier to be processed by the liver. Phototherapy can be administered on the postnatal ward or children's ward. If the jaundice level does not come down as expected, then this treatment may need to be 'intensified'. Click here for a video on phototherapy.
In very rare instances, where this treatment fails to control the rising level of bilirubin, they may need to undergo a process called an exchange transfusion - where almost all of the baby's blood is exchanged with matching donor blood. This is the most aggressive form of treatment that allows to bring down the bilirubin levels rapidly, thus preventing damage to their brain. Phototherapy lights are very effective these days and it is extremely rare for an exchange transfusion to be needed. In cases of blood group incompatibility, intravenous immunoglobulin may be given to prevent the need for an exchange transfusion.

Complications
In a vast majority of babies, jaundice does not lead to any long-term complications. However, in less than 1 in 100,000 babies, extremely high levels of jaundice may affect the baby's brain leading to a condition called kernicterus.
