Common Newborn Health Concerns (And When to Call the Pediatrician)

Apr 29, 2025

Welcoming a newborn into the world is a joyous and life-changing experience. Amid the excitement and wonder, however, it’s perfectly normal for parents to feel overwhelmed when it comes to their baby’s health. Newborns are delicate and can experience a range of common health issues that often leave parents asking: “Is this normal? Should I call the pediatrician?”

At Arlington Prime Pediatrics, we understand your concerns and are here to help you navigate the early days of your newborn’s life with confidence. In this guide, we’ll cover common newborn health concerns, when they require attention, and signs that mean it’s time to call your pediatrician.

1. Jaundice

What It Is: Jaundice causes a newborn’s skin and eyes to appear yellow. It’s due to an excess of bilirubin, a pigment produced during the breakdown of red blood cells.

Is It Normal? Mild jaundice is common in newborns and usually appears 2-4 days after birth.

When to Call the Pediatrician:

  • If jaundice appears within the first 24 hours after birth
  • If the yellow color spreads or deepens
  • If your baby is feeding poorly, seems very sleepy, or is not gaining weight

Early evaluation can prevent complications like kernicterus, a rare type of brain damage.

2. Feeding Difficulties

What It Is: Some newborns struggle with breastfeeding or bottle-feeding due to latch issues, tongue-tie, or low energy levels.

Is It Normal? Slight difficulties are expected in the early days, but persistent problems should be addressed.

When to Call the Pediatrician:

  • If your baby is not latching or feeding well
  • If there are fewer than 6 wet diapers per day after day 5
  • If your baby is not gaining weight

Lactation support and feeding consultations can make a world of difference.

3. Spitting Up and Reflux

What It Is: Spitting up is common in newborns due to an immature digestive system.

Is It Normal? Frequent, small spit-ups are usually not a concern if your baby is gaining weight.

When to Call the Pediatrician:

  • Forceful vomiting (projectile vomiting)
  • Blood or green-colored vomit
  • Poor weight gain or signs of dehydration

Your doctor may recommend adjustments in feeding techniques or, in rare cases, medical treatments.

4. Colic

What It Is: Colic is characterized by intense, unexplained crying for several hours a day, typically beginning at 2-3 weeks of age.

Is It Normal? Unfortunately, yes. Up to 20% of newborns experience colic.

When to Call the Pediatrician:

  • If the crying is accompanied by vomiting, fever, or poor feeding
  • If you suspect your baby is in pain beyond typical colic

Your pediatrician can rule out other causes and provide strategies to soothe your baby.

5. Diaper Rash

What It Is: Irritation of the skin in the diaper area, often caused by moisture and friction.

Is It Normal? Yes. Nearly all babies experience diaper rash at some point.

When to Call the Pediatrician:

  • If the rash is severe, bleeding, or blistering
  • If it does not improve with home care after 2-3 days
  • If your baby seems to be in pain during diaper changes

Prescription creams or antifungal treatments may be needed.

6. Breathing Irregularities

What It Is: Newborns often breathe irregularly, with periods of fast breathing followed by slower breaths.

Is It Normal? Generally yes, as long as your baby looks comfortable.

When to Call the Pediatrician:

  • Persistent grunting sounds with each breath
  • Flaring nostrils
  • Chest retractions (skin pulling in between ribs)
  • Bluish color around lips or face

Breathing concerns can signal infections or congenital issues requiring immediate attention.

7. Fever

What It Is: A rectal temperature of 100.4°F (38°C) or higher.

Is It Normal? No. Any fever in a newborn younger than 3 months is considered an emergency.

When to Call the Pediatrician:

  • Immediately if your baby has a fever

Prompt evaluation is critical to rule out infections like meningitis or sepsis.

8. Umbilical Cord Care

What It Is: The stump of the umbilical cord falls off naturally within 1-3 weeks after birth.

Is It Normal? Some redness or a few drops of blood as it falls off are normal.

When to Call the Pediatrician:

  • Foul-smelling discharge
  • Persistent bleeding
  • Redness or swelling around the navel

Signs of infection should never be ignored.

9. Constipation

What It Is: Newborns may go several days without a bowel movement, especially if formula-fed.

Is It Normal? It can be, provided your baby seems comfortable.

When to Call the Pediatrician:

  • Hard, pellet-like stools
  • Blood in the stool
  • Severe discomfort or straining

Your pediatrician can guide you on diet adjustments or treatments.

10. Rashes and Birthmarks

What It Is: Newborns often develop rashes like baby acne, erythema toxicum (a harmless newborn rash), or cradle cap.

Is It Normal? Yes, in most cases.

When to Call the Pediatrician:

  • If the rash worsens, becomes infected, or is accompanied by a fever
  • If you notice unusual birthmarks that grow or change shape rapidly

Early intervention ensures proper diagnosis and care.

11. Dehydration

What It Is: Lack of adequate fluids can quickly lead to dehydration in newborns.

Is It Normal? No. Newborns need consistent hydration.

When to Call the Pediatrician:

  • Fewer than 6 wet diapers a day
  • Dry mouth or cracked lips
  • Sunken soft spot (fontanelle) on the head

Immediate attention can prevent serious complications.

12. Crying

What It Is: Newborns communicate needs through crying: hunger, discomfort, fatigue, or overstimulation.

Is It Normal? Frequent crying is typical, but excessive crying can sometimes indicate an underlying issue.

When to Call the Pediatrician:

  • If crying is constant, inconsolable, or sounds different (high-pitched, weak)
  • If you suspect pain, injury, or illness

Never hesitate to reach out for guidance.
