Jaundice is one of the most common reasons newborns are seen after hospital discharge, and one of the most common things postpartum doulas notice in the first week at home. Most newborn jaundice is harmless. A small number of cases become severe, and the difference between the two is not something a doula can judge by eye. That makes this topic a clear example of the principle that runs through postpartum doula work: observe well, describe plainly, and refer promptly. This article sets out what current guidance from the American Academy of Pediatrics (AAP) and the UK’s National Institute for Health and Care Excellence (NICE) says, where the two differ, and what that means for a doula’s practice.
Key takeaways
Quick answer: jaundice is a yellow color of the skin and eyes caused by bilirubin building up in the blood. Most babies get some. A doula cannot tell how high a baby’s bilirubin is by looking, so any yellow color that is spreading, appeared in the first day, is deepening, or comes with poor feeding or unusual sleepiness should be reported to the baby’s clinician the same day.
- The AAP’s parent guidance says most babies have mild, harmless jaundice, but in rare cases bilirubin can get very high and cause brain damage, which is why bilirubin testing as recommended matters.
- A study of 122 healthy term newborns found that experienced clinicians agreed poorly on the extent of jaundice and that visual estimates correlated only weakly with measured bilirubin, so the authors concluded visual assessment is neither reliable nor accurate.
- US and UK guidance differ on testing. The AAP’s 2022 guideline revision supports measuring bilirubin on all newborns before discharge, while NICE says not to measure bilirubin routinely in babies who are not visibly jaundiced.
- Both emphasize the same warning: jaundice in the first 24 hours of life needs urgent medical attention.

What the research says
What parents are told. The AAP’s Jaundice in Newborns page (last updated August 2024) explains that bilirubin comes from red blood cells and is cleared by the liver, and that most babies develop jaundice in the first days because the liver takes a few days to get better at removing it. It says jaundice is best seen in white light such as daylight, usually appears first on the face and then moves to the chest, abdomen, arms and legs as bilirubin rises, and may be harder to see in babies with darker skin. It states that any baby with jaundice in the first 24 hours should have bilirubin measured right away, that all babies should have at least one bilirubin measurement by skin or blood test before discharge, and that babies discharged before 48 hours should usually be seen within 2 days. It lists factors for an earlier follow-up visit: a high bilirubin before leaving the hospital, birth more than 2 weeks early, jaundice in the first 24 hours, breastfeeding that is not yet going well, scalp bleeding or heavy bruising from delivery, and a parent or sibling who needed light therapy. It says parents should call the baby’s doctor if the skin turns more yellow, if the abdomen, arms or legs are yellow, if the whites of the eyes are yellow, or if the baby is hard to wake, fussy, or not nursing or taking formula well. It also says sunlight is not a safe treatment for jaundice and that most jaundice needs no treatment.
The page also gives timing for when to raise concern about duration: it asks parents to tell the doctor if jaundice lasts more than 2 weeks in a formula-fed baby or longer than 4 weeks in a baby who is mainly breastfed, and notes that jaundice is more common in breastfed babies, particularly when the baby is not getting enough milk because of low milk production or latch difficulty.
What the guideline changed. The AAP announced its revised clinical practice guideline (Kemper and colleagues, Pediatrics, September 2022) for infants born at 35 or more weeks of gestation. According to the AAP’s summary, the guideline replaces the 2004 version, recommends measuring bilirubin on all newborns before discharge, and raises the phototherapy and exchange transfusion thresholds by a narrow range because research since 2004 suggests bilirubin does not cause toxicity unless it reaches higher levels than previously thought. It also changes the way follow-up is timed: the difference between the phototherapy threshold and the infant’s current level guides when to measure again. The guideline’s committee chair is quoted as saying kernicterus is rare but devastating. Only the AAP’s summary of the guideline could be read, not the guideline’s full text, which sits behind the journal’s subscription. Details such as the exact threshold values, which clinicians use with charts or calculators, are therefore not described here.
What looking can and cannot tell you. Moyer, Ahn and Sneed’s 2000 study in Archives of Pediatrics & Adolescent Medicine asked experienced pediatric nurse practitioners, residents and attending physicians to judge the extent of jaundice in 122 healthy term newborns and compared those judgments with measured bilirubin. Agreement about jaundice at specific body sites was poor (0% to 23% beyond chance), and the correlation between estimated and actual bilirubin values was weak to moderate (0.43 to 0.54). The authors concluded visual assessment is neither reliable nor accurate and that the decision to test should rest on other factors as well. The study is old and used a convenience sample from one hospital, and today’s practice includes transcutaneous bilirubin meters, but the core message that a glance does not measure bilirubin is consistent with current guidance.
The UK approach. NICE’s guideline CG98 on jaundice in newborn babies under 28 days (published 2010, last updated October 2023) says parents, carers and healthcare professionals should all look for jaundice, preferably checking the naked baby in bright, natural light, examining the whites of the eyes and gums, and pressing lightly on the skin to check blanched skin. It adds that changes in skin pigmentation may be harder to see in darker skin, and says not to rely on visual inspection alone to estimate bilirubin. Unlike the AAP, it recommends that bilirubin not be measured routinely in babies who are not visibly jaundiced. For babies with suspected or obvious jaundice in the first 24 hours it calls for an urgent serum bilirubin within 2 hours and urgent medical review within 6 hours. For term babies with jaundice lasting more than 14 days (21 days for babies born before 37 weeks) it calls for further tests, including looking for pale chalky stools and dark urine. So the two countries agree on the high-risk situations and differ on whether every baby should be tested before discharge.

What this means for doulas
- Look, but do not rate. A doula can note whether the baby looks more yellow than yesterday, whether the whites of the eyes look yellow, and how far the color extends. Naming a “level” or saying a baby “just has physiologic jaundice” goes beyond scope.
- Know the same-day triggers. From the AAP and NICE: yellow color in the first 24 hours, color that is deepening or spreading to the abdomen, arms or legs, yellow whites of the eyes, a baby who is hard to wake or not feeding well, and pale chalky stools or dark urine staining the diaper. Where the baby’s clinician gives different instructions, follow those.
- Support feeding. Because the AAP links jaundice to inadequate intake and recommends breastfeeding at least 8 to 12 times a day in the first days, a doula can help with positioning, waking a sleepy baby to feed as the clinician advises, and logging feeds and diapers. Do not recommend supplementing or stopping breastfeeding, which is a clinical decision.
- Do not recommend sunlight. The AAP specifically says sun is not a safe treatment.
- Mind skin tone. Both sources note jaundice can be harder to see in darker skin. Look at the whites of the eyes and gums and ask the clinician about testing rather than relying on skin color.
Putting the evidence into practice
- Ask about follow-up. At the first visit, ask whether the baby had a bilirubin check before discharge, and when the next appointment is. Encourage the family to keep it.
- Look in good light. Check the baby in daylight when the parent is comfortable, without making it a test, and describe what you see.
- Keep a simple log. Feeds, wet and BM diapers (including stool color), alertness. Bring it to the call or visit.
- Escalate quickly. If the baby looks more yellow, is hard to wake, feeds poorly or has pale chalky stools or dark urine, encourage the parent to call the pediatric provider immediately. If the baby seems very ill, or the parent cannot reach anyone, say so plainly and advise emergency care.
- Document and follow up. Note what you observed, what you told the family and what they planned to do.

Limits and uncertainty
Guidelines differ by country, and the US and UK recommendations summarized here apply to term and near-term babies, not to preterm or ill infants. This article draws on the AAP parent pages and press summary and the full NICE recommendations, but not the AAP guideline’s full text, so it does not describe its treatment thresholds, risk calculation or phototherapy details. The study on visual assessment is from 2000 and tested a small group in one hospital. Because jaundice is harder to see in darker skin, visual cues are a weaker tool for some families than others. Doulas work in different settings and many states do not regulate their role, so a doula should follow the baby’s clinician instructions and any employer or agency protocol.
The bottom line
Jaundice is usually harmless, occasionally dangerous and impossible to grade by looking. A doula’s job is to notice, to encourage feeding and follow-up, and to push for same-day contact with the baby’s clinician when the color deepens or spreads, appears in the first day, or comes with sleepiness, poor feeding, pale stools or dark urine.
