Jaundice is a common condition in newborns, affecting a significant number of babies during the first few days of life. While it can cause concern for parents, it is often a normal part of a newborn’s development. Understanding when jaundice is normal and when it may indicate a more serious condition is essential for early detection and proper management.
What is Jaundice in Newborns?
Jaundice is a condition that occurs when a newborn’s skin, and sometimes the whites of their eyes, turn yellow. This yellowing happens due to the accumulation of a substance called bilirubin in the baby’s blood. Bilirubin is a yellow pigment that is produced during the normal breakdown of red blood cells. Normally, the liver processes bilirubin and excretes it from the body. However, in newborns, the liver may not be fully developed enough to effectively process bilirubin, leading to its buildup.
Most newborns experience some degree of jaundice, and in many cases, it is a temporary and harmless condition that resolves on its own. This type of jaundice is often referred to as physiological jaundice, and it typically appears within the first few days of life.

Physiological Jaundice: When is it Normal?
Physiological jaundice is the most common type of jaundice in newborns. It usually begins to appear two to three days after birth, peaks around the fourth or fifth day, and then gradually disappears by the end of the second week of life. This type of jaundice is considered normal and is a result of the baby’s immature liver not being able to process and eliminate bilirubin quickly enough.
In full-term, healthy newborns, physiological jaundice is typically mild and does not require any specific treatment. However, healthcare providers will monitor bilirubin levels to ensure they do not rise to a point where they could cause complications.
Key characteristics of physiological jaundice:
Appears two to three days after birth
Peaks around day four or five
Gradually fades within two weeks
No other symptoms present, such as lethargy or poor feeding
Breastfeeding Jaundice: A Common Variation
Breastfeeding jaundice is another common form of jaundice that occurs in the first week of life. This is not caused by breastfeeding itself, but rather by the fact that some babies do not get enough breast milk during the first few days. This can happen if the baby is not latching properly or if the mother’s milk has not come in yet. Insufficient intake of breast milk leads to dehydration and a slower passage of bilirubin through the baby’s digestive system, allowing it to build up in the blood.
Breastfeeding jaundice typically resolves once the baby starts to receive enough milk. Encouraging frequent feedings and ensuring proper latch can help reduce the severity of breastfeeding jaundice.
Breast Milk Jaundice: A Prolonged Form of Jaundice
In some cases, jaundice may persist beyond the first week and continue for several weeks. This is referred to as breast milk jaundice. This form of jaundice is different from breastfeeding jaundice, as it is thought to be caused by certain substances in the breast milk that interfere with the liver’s ability to process bilirubin.
Breast milk jaundice usually appears after the first week of life and can last for a month or more. Despite the prolonged jaundice, babies with breast milk jaundice are generally healthy, feeding well, and gaining weight normally. This type of jaundice does not indicate any problems with breastfeeding, and it is not harmful to the baby.
If breast milk jaundice persists for an extended period, the healthcare provider may recommend monitoring the baby’s bilirubin levels, but in most cases, no treatment is required. The condition will resolve on its own as the baby’s liver matures and becomes better at processing bilirubin.
When to Seek Medical Advice: Warning Signs of Pathological Jaundice
While physiological jaundice, breastfeeding jaundice, and breast milk jaundice are usually harmless and resolve on their own, there are cases where jaundice may indicate an underlying problem. This is known as pathological jaundice, and it can occur due to various conditions that affect bilirubin production or elimination.
It is important to be aware of the signs that suggest jaundice may be more serious:
Jaundice that appears within the first 24 hours of life
Very high bilirubin levels that continue to rise rapidly
Jaundice lasting longer than three weeks
Poor feeding, extreme lethargy, or difficulty waking the baby
Dark urine or pale stools
Yellowing that spreads to the arms, legs, or abdomen
If any of these signs are present, the baby should be evaluated by a healthcare provider immediately. Pathological jaundice can be caused by several conditions, including:
Blood type incompatibility (such as Rh incompatibility)
Infections
Genetic disorders
Liver problems
In these cases, prompt medical intervention is necessary to prevent complications.
Monitoring and Treatment of Newborn Jaundice
How is jaundice diagnosed?
Most newborns are routinely checked for jaundice before leaving the hospital. The healthcare provider will assess the baby’s skin color and may use a device called a transcutaneous bilirubinometer to measure bilirubin levels through the skin. If the bilirubin levels are high or the jaundice appears early, a blood test may be performed to get a more accurate measurement of bilirubin levels.
Phototherapy: A Common Treatment for Severe Jaundice
In cases where bilirubin levels are higher than normal, phototherapy may be recommended. Phototherapy is a treatment that uses special blue lights to help break down bilirubin in the baby’s skin, allowing it to be more easily excreted from the body. This treatment is safe and effective, and it is commonly used for babies with moderate to severe jaundice.
During phototherapy, the baby is placed under the lights, wearing only a diaper and eye protection. The treatment may be done in the hospital or, in some cases, at home with portable phototherapy units.
Exchange Transfusion: A Rare but Necessary Intervention
In rare cases, when bilirubin levels are extremely high and phototherapy is not effective, an exchange transfusion may be needed. This procedure involves replacing the baby’s blood with donor blood to quickly lower bilirubin levels. While exchange transfusion is rarely required, it is a life-saving procedure for babies with very high bilirubin levels.
How to Support a Newborn with Jaundice at Home
For mild cases of jaundice, there are simple steps that parents can take at home to help lower bilirubin levels:
Frequent feedings: Ensuring that the baby is feeding well and frequently helps promote bowel movements, which assist in the excretion of bilirubin.
Sunlight exposure: Exposing the baby to indirect sunlight for short periods can help break down bilirubin in the skin. However, this should be done with caution, and direct sunlight should be avoided to prevent sunburn.
Parents should continue to monitor their baby’s skin color and feeding habits, and follow any recommendations from the healthcare provider regarding follow-up appointments or bilirubin tests.
Conclusion
Jaundice is a common and typically normal condition in newborns. Physiological jaundice, breastfeeding jaundice, and breast milk jaundice are usually harmless and resolve on their own. However, it is important for parents to be aware of the signs of pathological jaundice, which can indicate a more serious underlying condition. Early detection and treatment of jaundice are essential for preventing complications and ensuring the health and well-being of the baby. If there is any concern about jaundice, seeking advice from a healthcare provider is always the best course of action.
