How to Tell if Your Baby is Too Hot or Too Cold

Learn the essential signs to monitor your baby's temperature and ensure their comfort and safety

🌡️ Understanding Baby Body Temperature

Normal baby temperature: ~97.5°F (36.4°C), with fever defined as ≥100.4°F (38°C)

Babies can't regulate temperature well until approximately 9-12 months old, making it crucial for parents to monitor and adjust their environment.

Best indoor sleeping temperatures: 68-72°F (20-22°C) - This range helps prevent both overheating and getting too cold during sleep.

🔥 Signs Your Baby Is Overheating

Key Warning Signs:

  • •Warm or hot skin: Especially on the neck, ears, back, or tummy
  • •Flushed or red cheeks and skin
  • •Excessive sweating/damp hair, especially at the neck
  • •Rapid heartbeat or breathing (tachycardia)
  • •Restless, irritable, lethargic, or unusually quiet behavior
  • •Dizziness, vomiting, confusion, or unresponsiveness — medical attention needed immediately

What to Do:

  • ✓Feel torso—not hands/feet; check neck/back for accurate temperature assessment
  • ✓Remove layers; use lighter clothing, lower the room temperature to ≤75°F (23.8°C)
  • ✓No hats or heavy bedding, especially during sleep
  • ✓Ventilate the room; use fans thoughtfully (not directly on baby)
  • ✓Ensure hydration (feed more frequently)
  • ✓Seek medical care for severe signs

❄️ Signs Your Baby Is Too Cold

Key Warning Signs:

  • •Cool skin on chest/neck/back, sometimes hands and feet
  • •Pale complexion
  • •Shivering — a clear thermoregulation response
  • •Fussiness, unsettled waking, especially around early morning hours
  • •Excess movement in their crib as they try to self-warm

What to Do:

  • ✓Confirm room temp: aim for 68-72°F (20-22°C)
  • ✓Add layers: onesie → pajamas → sleep sack (increase TOG rating)
  • ✓Use warmer fabrics (wool/synthetics), avoid hats during sleep
  • ✓Avoid loose blankets in cribs—use wearable sleep sacks safely
  • ✓If core remains cold despite layers and room adjustment → wrap baby and monitor; consult a doctor if symptoms persist

Remember

Always trust your instincts as a parent. If you're concerned about your baby's temperature or comfort, don't hesitate to consult with your pediatrician. Regular monitoring and adjustments based on your baby's individual needs will help ensure they stay comfortable and safe.
