Care of Common Problems in the Newborn

Core Concepts

Physiologic jaundice: expected, but only on its own timeline

Jaundice is the yellow discoloration from bilirubin, a byproduct of red blood cell breakdown. Newborns produce more bilirubin than older children (more red cells, shorter lifespan) and their immature livers clear it more slowly, so a mild rise is normal. Physiologic jaundice typically appears after the first 24 hours of life, peaks around days 3–5 in term newborns, and resolves as feeding increases and the liver matures. The nursing priorities are feeding well (stooling removes bilirubin), watching the pattern of jaundice (onset, spread, and progression), and following the facility's bilirubin-monitoring protocol. Jaundice that appears in the first 24 hours, rises rapidly, reaches the palms and soles, or is accompanied by lethargy or poor feeding is not physiologic — it requires prompt provider evaluation because very high bilirubin can damage the brain (kernicterus). Sunlight exposure is not a safe home treatment; monitoring and any treatment follow provider orders.

Common skin findings: alarming to look at, benign underneath

• Erythema toxicum — blotchy red patches with tiny white or yellow papules, often appearing in the first days. It looks dramatic but is harmless, comes and goes, and requires no treatment.
• Milia — tiny white cysts on the nose, cheeks, and chin, from blocked sebaceous glands; they resolve on their own.
• Neonatal acne — small red bumps or pustules on the face, driven by maternal hormones; it clears without treatment.
• Mongolian spots — flat, blue-gray patches, often over the lower back and buttocks, more common in newborns with darker skin; they are pigmentation, not bruising, and fade over years.
• Peeling skin — normal shedding, especially in post-term newborns.

Oral findings: thrush versus milk curds

Epstein pearls are tiny white cysts on the gums or palate — normal and self-resolving. Thrush (oral candidiasis) appears as white patches on the tongue, gums, or inner cheeks that do not wipe away — scraping them leaves a red, sometimes bleeding base. Milk curds, by contrast, wipe off easily. Thrush can make feeding uncomfortable and may require provider-prescribed treatment; it can also coexist with diaper-area candidiasis.

Feeding and gastrointestinal concerns: spitting up versus vomiting

Most newborns spit up small amounts after feeds — effortless, small-volume, and painless — because the lower esophageal sphincter is immature. Parents should know this is normal as long as the baby is gaining weight and not distressed. Vomiting is forceful, large-volume, and often projectile; projectile vomiting in particular, or vomiting with blood, bile (green), poor weight gain, or signs of dehydration, requires evaluation. Dehydration warnings include fewer wet diapers than expected, a dry mouth, a sunken fontanelle, and lethargy. Infrequent stooling is not automatically constipation — many breastfed babies stool rarely after the early weeks — but hard, difficult-to-pass stools or no stool by the expected early window need assessment.

Umbilical and diaper-area concerns

An umbilical granuloma is a small, moist pink nodule on the stump after it falls off; it is usually harmless and treated per provider instructions. The stump itself can become infected (omphalitis) — warning signs are redness spreading onto the belly, warmth, swelling, drainage, or odor, and the baby may be febrile or lethargic. Diaper dermatitis (diaper rash) is common, usually from moisture and friction; prevention is frequent changes, gentle cleaning, drying, and barrier cream as taught. A rash with satellite red dots or one that does not improve may be fungal and needs provider assessment.

Red flags: when "common" stops being common

Any of the following warrants prompt provider notification: temperature outside the expected range for the facility's policy, poor feeding or lethargy, respiratory distress (fast or labored breathing, grunting), worsening jaundice, projectile vomiting or bile-stained vomit, blood in stool, seizure-like movements, vesicles or blisters on the skin, and umbilical redness with drainage or odor. The nurse's documentation of these findings — onset, timing, and progression — is the information the provider needs to act.

How It Works / Step-by-Step Process

1. Identify the finding and anchor it in the baby's age: is this expected at this day of life?
2. Gather the pattern: onset, timing, progression, and any associated signs (feeding, output, temperature, behavior).
3. Apply the facility's assessment tools (e.g., jaundice risk assessment, bilirubin protocol, vital-sign criteria).
4. For benign findings: document, reassure the family with accurate information, and teach what to watch.
5. For red flags: notify the provider promptly with a clear, factual description; follow orders.
6. Document teaching, family understanding, and any follow-up plan; escalate scope issues per policy.
