What is normal? — Newborn Safety — When to Call the Pediatrician

What's usually within range, and when to call.

← All "what is normal?" guidesFull evidence topic →

Below are common situations related to Newborn Safety — When to Call the Pediatrician. Each pairs a plain-language "usually within the range of normal" note with concrete signs to call your care team. If something feels wrong that isn't listed, call anyway.

  • Fever — any temperature ≥100.4°F (38°C) rectally in a baby under 3 months

    Within the range of normal

    Being flushed after crying, being over-bundled, or being warm from skin-to-skin does NOT cause a true fever. A rectal temp is the accurate reading in the first months.

    Call your healthcare team if

    ≥100.4°F (38°C) rectally in a baby under 3 months → go in NOW (ER or call the pediatrician for direct admission). Do NOT give acetaminophen before evaluation; it masks the picture. Under 8 weeks especially, sepsis, UTI, and meningitis are ruled out with blood, urine, and sometimes spinal fluid. In babies 3–6 months, fever with poor feeding, lethargy, or trouble breathing is also same-day.

  • Breathing trouble

    Within the range of normal

    Newborns breathe fast (40–60 breaths/minute) and irregularly, with brief pauses of a few seconds followed by faster breaths (periodic breathing). Sneezing and occasional congestion are common.

    Call your healthcare team if

    Breathing pauses ≥20 seconds, or any pause with color change or limpness. Persistent grunting on each breath. Nostrils flaring with each breath. Skin pulling in between or under the ribs (retractions). Breathing >60/minute at rest. Blue or dusky lips/tongue/face — 911. Bark-like cough or high-pitched sound on inhale — same day. Wheezing or clear trouble taking a breath — same day.

  • Jaundice — how yellow is too yellow

    Within the range of normal

    Mild jaundice appearing on the face after day 2, peaking around day 3–5, is expected in ~60% of term babies and usually resolves on its own with good feeding.

    Call your healthcare team if

    Any yellow color in the first 24 hours of life. Yellow that spreads to the chest, belly, arms, or legs (yellow moves head-to-toe as bilirubin rises). Whites of the eyes deep yellow. Baby who is very sleepy, hard to wake, feeding poorly, or has a high-pitched cry — go in same day for a bilirubin check. Do not visually guess with dark skin — jaundice is harder to see and needs a measured level.

  • Dehydration — wet diapers and weight

    Within the range of normal

    Day-of-life rule: at least as many wet diapers as days old in the first week, working up to 6+ wet and 3+ stools per day by day 5–7. Concentrated urine in the first days is expected; "brick dust" (orange-pink urate crystals) is common up to day 3.

    Call your healthcare team if

    Fewer wet diapers than the day-of-life number, brick-dust urine AFTER day 3, no stool for 24 hours in a newborn who has already passed meconium, sunken soft spot, dry mouth, no tears (in a baby old enough for tears), or weight loss ≥10% from birth weight. Sleepiness plus poor output = call same day. Signs of severe dehydration (very sunken eyes, cold hands/feet, unresponsive) — 911.

  • Lethargy — sleepy vs. hard to wake

    Within the range of normal

    Newborns sleep 16–18 hours a day and often need to be woken for feeds in the first weeks. A drowsy baby who wakes to a diaper change, undressing, or a cool cloth and then feeds is normal.

    Call your healthcare team if

    Baby is hard to wake for feeds, doesn't rouse to being undressed or a cool cloth, feels floppy when picked up, feeds much less vigorously than usual, cries weakly or high-pitched, or 'just doesn't seem right' — call same day. In a young baby, lethargy is a serious symptom, especially with fever, poor feeding, jaundice, or few wet diapers.

  • Feeding refusal or poor feeding

    Within the range of normal

    Cluster feeding (long stretches of near-constant feeding, especially evenings) and one shorter or slightly disorganized feed in a stretch is normal. Growth spurts around day 7–10 and 3 weeks bump up demand.

    Call your healthcare team if

    Refuses more than 2 feeds in a row, isn't waking for feeds (see lethargy), can't stay latched or coordinate suck-swallow-breathe, chokes or turns blue with feeds, vomits after MOST feeds (not just spit-up), or diaper output has dropped — call same day.

  • Vomiting — spit-up vs. concerning

    Within the range of normal

    Small amounts of milk that dribble out during or after feeds ('spit-up') are common and don't require treatment if the baby is comfortable and gaining weight.

    Call your healthcare team if

    Forceful/projectile vomiting, green or yellow (bilious) vomiting, blood in the vomit, vomiting after every feed with poor weight gain, or vomiting with a swollen belly — go in same day. Bilious vomiting can signal a bowel obstruction (malrotation) and is an emergency.

  • Stool changes and blood

    Within the range of normal

    Meconium (black, tarry) in the first 24–48 hours, then transitional (green-brown), then yellow seedy (breastfed) or tan/pasty (formula-fed). Frequency varies from many times a day to once every few days after ~6 weeks.

    Call your healthcare team if

    No stool in the first 24–48 hours of life, pale/white/chalky stool at any age (can signal liver disease — same day), red blood in stool (more than a tiny streak), black stool AFTER meconium has passed, or persistent watery diarrhea with dehydration signs.

  • Color changes — pale, blue, gray, or mottled

    Within the range of normal

    Blue hands and feet (acrocyanosis) in a warm-bodied newborn in the first day or two is normal. Mild mottling when cold that resolves with warming is normal. Pink flushing when crying is normal.

    Call your healthcare team if

    Blue or gray around the LIPS, TONGUE, or FACE — 911. Persistent pallor (white/washed out), especially with poor feeding or fast breathing. Persistent mottling in a warm baby. A blue spell with feeding.

  • Unusual movements or seizure

    Within the range of normal

    Startle (Moro) reflex to loud sounds, brief jerky movements when falling asleep or waking (sleep myoclonus) that STOP when you gently hold the arm or leg, and lots of squirming are all normal.

    Call your healthcare team if

    Rhythmic jerking that does NOT stop when you hold the limb, sustained stiffening, staring with eye deviation or lip-smacking, or any episode with color change or unresponsiveness — 911 or ER. A history of any of these — same-day evaluation even if the baby looks fine now.

  • Cord and circumcision care

    Within the range of normal

    The umbilical stump dries and falls off in 1–3 weeks. A small amount of dried blood or crustiness when it separates is normal. A circumcised penis is red and swollen for the first days; yellow film (granulation) is normal and NOT infection.

    Call your healthcare team if

    Spreading redness around the base of the cord, foul smell, pus, active bleeding you can't stop with gentle pressure, or fever with any of the above — same day. For circumcision: bleeding that soaks a diaper, unable to pee, or spreading redness beyond the head of the penis — same day.

  • Head injury and falls

    Within the range of normal

    Newborn heads are protected by soft skull plates and reflexes, but any fall in the first months is worth a call because you can't easily assess a young baby.

    Call your healthcare team if

    ANY fall from a surface (bed, changing table, arms) in a baby under 6 months — call the pediatrician the same day. Vomiting after a bump to the head, unresponsiveness, seizure, bulging soft spot, or unequal pupils — 911.

  • Trust your gut

    Within the range of normal

    You will know your baby's normal better than any list. A baby who is feeding well, has appropriate wet/dirty diapers, is gaining weight, and 'seems like themselves' is almost always fine.

    Call your healthcare team if

    You feel something is off and you can't say what. Call. This is a specific reason to call — pediatricians take 'my baby doesn't seem right' seriously in a young infant.
