One of the first things parents worry about with a newborn is their temperature. Babies can’t yet tell us when they’re feeling too hot or too cold, so it’s up to us to recognize the signs and act quickly. Monitoring your little one’s temperature helps keep them safe, healthy, and comfortable.
In this post, we’ll cover:
✨ What’s considered a normal temperature for newborns
✨ How to check your baby’s temperature safely
✨ Signs of fever or low body temperature
✨ Remedies and when to call the doctor
✨ Parent-friendly tips for keeping your baby just right
🌈 What Is a Normal Temperature for a Newborn?
The normal temperature range for a newborn is:
👉 97.5°F (36.4°C) – 99.5°F (37.5°C)
Anything above or below this range may need attention.
- Fever: 100.4°F (38°C) or higher
- Low temperature (hypothermia): Below 97°F (36.1°C)
💡 Remember: Babies’ bodies can’t regulate heat as well as adults, which is why they can get cold or overheat much faster.
🍼 How to Check Your Baby’s Temperature
Not all thermometers are equal when it comes to newborns. Here are the best methods:
- Rectal thermometer 🌟 (most accurate for newborns)
- Temporal (forehead) thermometer (good for quick checks)
- Underarm thermometer (less accurate but can be used for screening)
⚠️ Avoid ear thermometers for newborns under 6 months—they’re not reliable at this age.
🚨 Signs Your Baby’s Temperature Is Not Right
Signs of Fever
- Flushed skin
- Irritability or fussiness
- Sleepiness
- Warm to the touch
- Poor feeding
Signs of Low Temperature
- Cool skin, especially hands and feet
- Lethargy (very sleepy or difficult to wake)
- Weak cry
- Trouble breathing
🌿 Remedies & What Parents Can Do
For Fever:
- Dress your baby in light clothing
- Keep the room at a comfortable temperature (68–72°F / 20–22°C)
- Offer frequent feeds to prevent dehydration
- Never give over-the-counter medicine without your pediatrician’s advice
For Low Temperature:
- Add a layer of clothing or swaddle (not too tight)
- Skin-to-skin contact (a natural warmer for your baby)
- Adjust room temperature to a cozy range
- Use a hat or socks if the room feels cool
🧑⚕️ When to Call the Doctor Immediately
Call your pediatrician or seek medical help if:
✅ Your newborn (under 3 months) has a fever of 100.4°F (38°C) or higher
✅ Baby’s temperature is below 97°F (36.1°C) and not improving with warming measures
✅ Baby shows signs of dehydration (dry mouth, fewer wet diapers)

💕 Parent-Friendly Tips to Keep Baby’s Temperature Just Right
- Follow the “one more layer rule”: Dress your baby in the same number of layers as you’re wearing—plus one extra.
- Use a sleep sack instead of blankets (safer and cozier).
- Keep the nursery cool but not cold.
- Trust your instincts—if your baby feels too hot or too cold, check their temperature.
