Expert Tips for Accurate Readings
👶 For Newborns
Always use a rectal thermometer for the most accurate reading. Clean thoroughly before and after use.
🌡️ For Ear Thermometers
Pull the ear gently back to straighten the ear canal for a more accurate reading.
📏 Consistency Matters
Use the same method each time to track fever trends reliably. Note that armpit readings are less accurate.
🧼 Clean After Use
Disinfect the probe with rubbing alcohol or soapy water to prevent cross-contamination.
