Overview
The newborn period lasts from birth to 28 days of age. During this time, babies are learning to breathe, feed, regulate body temperature, and sleep outside the womb. Good newborn care includes feeding support, skin-to-skin contact, warmth, clean care practices, and routine health checks.
Key Symptoms
Healthy newborns often sleep a lot, wake for feeds, pass urine and stool regularly, and may lose a small amount of weight before gaining it back. Common temporary changes can include mild skin peeling, hiccups, sneezing, and brief irregular breathing pauses. Symptoms that are more concerning include poor feeding, unusual sleepiness, fever, trouble breathing, yellowing of the skin or eyes that is spreading or worsening, fewer wet diapers, vomiting that is forceful or green, and seizures or unusual movements.
Causes and Risk Factors
Newborn health problems may be linked to prematurity, low birth weight, difficult delivery, birth defects, infections, jaundice, feeding problems, or lack of oxygen around the time of birth. Risk can also be higher if the baby is born to a parent with certain infections or medical conditions, or if there was limited pregnancy or birth care. Unsafe sleep environments, cold stress, and poor hygiene can also increase the chance of harm.
Who Is Affected
All newborns need close observation and care, but some need extra attention. Babies born early, very small babies, twins or other multiples, and babies with medical complications are at higher risk of illness. Newborns in places with limited access to skilled birth care, clean water, vaccines, or follow-up services may also face greater health risks.
Prevention
Many newborn problems can be reduced with quality care before birth, skilled care during delivery, and early care after birth. Helpful steps include skin-to-skin contact, breastfeeding support, keeping the baby warm, clean cord care, handwashing, timely immunizations, and newborn screening where available. Safe sleep is also important: place babies on their backs to sleep on a firm, flat surface without loose bedding or soft objects.
Diagnosis and Tests
Healthcare professionals assess newborn health by checking breathing, temperature, heart rate, feeding, weight, skin color, activity, and hydration. A baby may also have screening tests after birth, such as blood spot screening, hearing screening, and checks for jaundice, depending on local health systems. If a problem is suspected, testing may include blood tests, oxygen measurement, or imaging.
Treatment Categories
Treatment depends on the baby’s needs and may include feeding support, extra warmth, phototherapy for jaundice, oxygen, treatment for infection, or specialized care in a neonatal unit. Some babies only need observation and follow-up, while others need urgent hospital care. Parents and caregivers should follow the newborn care plan given by their healthcare team.
Living With It
Caring for a newborn involves learning feeding cues, sleep patterns, diaper changes, and ways to soothe the baby. It is normal for caregivers to need guidance and support, especially in the first days and weeks. Keep all follow-up visits, ask about screening results, and seek help early if feeding, breathing, color, or alertness changes.
When to Seek Medical Care
Seek medical care promptly if a newborn is feeding poorly, has a fever or low temperature, seems unusually sleepy, has worsening jaundice, fewer wet diapers, vomiting, diarrhea, or signs of infection around the umbilical cord. Also get medical advice if the baby is not waking for feeds, is losing too much weight, or if you are worried about breathing or dehydration. Newborns should not be monitored at home for serious symptoms without professional advice.
When It May Be an Emergency
Get emergency care immediately if a newborn has trouble breathing, turns blue or very pale, has a seizure, becomes limp, is hard to wake, has green vomit, or has a fever in early infancy according to local emergency guidance. Emergency care is also needed after choking, pauses in breathing, severe dehydration, or any sudden major change in responsiveness. If emergency services are available where you live, contact them right away.
