Newborn jaundice is something we see all the time in the first days of life, and in many cases it’s a completely normal part of a newborn’s transition after birth.
Jaundice happens when bilirubin builds up in the body, leading to the yellowing of a baby’s skin and eyes. Because newborns have a higher red blood cell turnover and their livers are still maturing, bilirubin can temporarily rise in those early days.
Most of the time, this type of jaundice is what we call physiologic, meaning it peaks around days 3–5 and gradually resolves as the body learns to process bilirubin more efficiently.
But it’s also something we monitor closely. Appearance alone isn’t enough to determine bilirubin levels, which is why pediatricians often use tools like bilirubin measurements and age-based charts to guide care and decide if treatment is needed.
The good news? When intervention is necessary, treatments like phototherapy are very effective.
If you ever notice yellowing of your baby’s skin or eyes, changes in feeding, or difficulty waking your newborn, it’s always best to reach out to your pediatric provider to take a closer look.
