Rectal thermometers are considered the gold standard for infants under 3 months. For older babies, temporal artery (forehead) thermometers offer excellent accuracy with less invasiveness.
Can I use a regular digital thermometer for my baby?
It's best to use a thermometer specifically designed for infants. They have faster response times, flexible tips, and age‑appropriate safety features.
How often should I replace my digital thermometer?
Most digital thermometers last for several years if properly maintained. Replace the battery when readings become inconsistent, or if the device shows signs of wear.
