Infant Fever
Rectal temperature of 38.0°C (100.4°F) or higher in an infant under 3 months is treated as an emergency until a clinician rules out serious infection.

Infant Diseases, Baby Symptoms & Newborn Care
Educational articles on infant fever, newborn jaundice, baby colic, baby rash, baby cough, RSV, dehydration, umbilical cord care, and safe sleep. This is not a diagnosis.
Newborn Jaundice
Jaundice is yellowing of the skin and eyes from bilirubin. It is common after the first 24 hours of life, but day-one yellow color, rapidly deepening color, or poor feeding needs prompt clinical review.
Read guideBaby Colic
Colic is prolonged, recurrent crying in an otherwise thriving infant, often in the evening during the first three months. It is a diagnosis of exclusion after infection and a surgical abdomen are considered.
Read guideBaby Rash
Most infant rashes are irritant, heat-related, or seborrheic. A rash with fever, spreading redness, or a newborn who looks unwell is a different problem and needs same-day clinical review.
Read guideBaby Cough
Cough is a symptom, not a diagnosis. Causes range from a common cold to bronchiolitis, pertussis, or aspiration. Infants do not receive over-the-counter cough suppressants.
Read guideDiaper Rash
Irritant diaper dermatitis comes from moisture and stool enzymes. Yeast adds satellite spots and fold involvement. Open sores and fever are not routine home-barrier problems.
Read guideCradle Cap
Cradle cap is common greasy scalp scale. It is not a hygiene failure. Never scrape the fontanelle.
Read guideBaby Reflux
Effortless spit-up is often physiologic. GERD implies pain, poor weight gain, or respiratory events. Back-sleep remains mandatory.
Read guideOral Thrush
Thrush is Candida in the mouth. Milk residue wipes away; thrush plaques usually do not. Household dyes and vinegar are not treatments.
Read guideBaby Cold
Colds are viral. Young infants are nose-breathers, so congestion can interrupt feeding. Honey is forbidden under 12 months.
Read guideRSV in Babies
Respiratory syncytial virus can cause bronchiolitis or apnea in young and premature infants, especially in winter.
Read guideInfant Bronchiolitis
Bronchiolitis is viral inflammation of small airways. Supportive care is primary.
Read guideInfant Dehydration
Infants lose fluid faster than older children. Wet-diaper counts are a practical home signal, not a lab test.
Read guideNewborn Umbilical Cord Care & Infection Warning Signs
Keep the stump dry and above the diaper fold. A spreading red ring, foul discharge, or fever is omphalitis until proven otherwise.
Read guideSafe Sleep, Room Temperature & SIDS Prevention
Alone, on the back, in a crib: firm mattress, fitted sheet only. Illness is not a reason to add pillows or incline the sleeper.
Read guidePyloric Stenosis
This is not a home-care condition. Do not wait it out with thickened feeds.
