Bottom line
Newborns can become unwell quickly. Fever, breathing trouble, blue color, limpness, seizure, poor feeding, fewer wet diapers, or unusual sleepiness should be handled with prompt medical advice, not just online reassurance.
Fever
For a young newborn, fever is a reason to contact a clinician urgently. Follow your local guidance on the exact temperature threshold and how to measure it. Do not give medicine to a newborn without clinician guidance.
Breathing and color
Seek urgent help for fast or labored breathing, grunting, pauses that worry you, ribs pulling in, blue lips or face, or a baby who looks pale, gray, or floppy.
Feeding and diapers
Call for advice if your baby is too sleepy to feed, feeds much less than usual, repeatedly vomits, or has fewer wet diapers than expected. Poor intake and low urine output can signal dehydration or illness.
Behavior
Trust a strong parental concern. A newborn who is hard to wake, unusually weak, has a seizure, has a bulging soft spot, or does not seem like themselves needs prompt assessment.
What to say when calling
Say the baby's age in days or weeks, temperature and measurement method, feeding amount/frequency, wet diaper count, breathing observations, color, and whether the baby wakes for feeds.
Educational note
