    Care Advice for Mild Jaundice

    What You Should Know:

    • Some jaundice is present in 50% of newborns.
    • It lasts a short time and will go away. Most often, it is harmless.
    • The first place for jaundice to start is in the whites of the eyes.
    • Jaundice that is only of the face and eyes is always harmless.
    • Here is some care advice that should help.


    • If bottle fed, increase how often you feed your baby.
    • Try to feed every 2 to 3 hours during the day.
    • Don’t let your baby sleep more than 4 hours at night without a feeding.


    • If breastfed, increase how often your feed your baby.
    • Nurse your baby every 1½ to 2 hours during the day.
    • Don’t let your baby sleep more than 4 hours at night without a feeding.
    • Goal: At least 10 feedings every 24 hours.

    Increase Stools:

    • If your baby is 5 days or older AND has less than 3 stools per day, try to increase stools. Do this by carefully putting a lubricated thermometer into the anus. Put it in no more than ½ inch (12 mm). Then, gently move it from side to side a few times. This will help your baby pass a stool.
    • Reason: Increased stools carry more bilirubin out of the body.
    • Do this once or twice per day until jaundice improves. Also, do this until stool frequency becomes normal.

    What to Expect:

    • Physiological jaundice peaks on day 4 or 5.
    • It slowly goes away over 1-2 weeks.

    Judging Jaundice:

    • Jaundice starts on the face and moves downward. Try to determine where it stops.
    • View your baby unclothed in natural light near a window.
    • Press on the skin with a finger to remove the normal skin tone.
    • Then try to look if the skin is yellow before the pink color returns.
    • Move down the body, doing the same. Try to look where the yellow color stops.
    • Jaundice that only involves the face and eyes is always harmless. As it involves the chest, the level is going up. If it involves the stomach, arms or legs, the bilirubin level needs to be checked.

    Call Your Doctor If:

    • Jaundice gets worse
    • Legs turn yellow
    • Feeds poorly or has a weak suck
    • Baby starts to look or act abnormal
    • Jaundice lasts more than 14 days
