Forehead Thermometer vs Other Methods
Forehead thermometers vs other measurement sites in babies
The short version
Non-contact forehead thermometers are quick and tolerated by a sleeping baby, and they are less accurate than the methods clinicians rely on in very young infants. For newborns, guidance in most countries points to a specific method for a reliable core reading, and a fever in a very young baby is urgent regardless of how it was measured. Own a forehead thermometer for convenience; follow your doctor on which reading they want.

Choose the No-Touch Forehead Thermometer if…
You want a reading without waking a sleeping baby, or a quick check through the day. It is genuinely convenient and it is the reading you take between the ones that matter.
Choose the Electric Nasal Aspirator if…
Blocked noses stop babies feeding and sleeping and cannot be cleared by blowing. An aspirator with saline drops is one of the most useful things to own before the first cold arrives.
Common questions
What temperature is a fever?
Commonly 38C or 100.4F and above, and the number matters far less than the age of the baby. In an infant under three months any fever is a reason to contact a doctor promptly rather than to monitor at home.
Which thermometer do doctors prefer for babies?
Guidance varies by country, and for very young infants a method giving a reliable core temperature is usually specified. Ask your health visitor or paediatrician which they want you to use and report.
What should I do about a fever?
Contact your doctor for young infants, and for older babies watch how the child is rather than the number. Poor feeding, unusual drowsiness, a rash that does not fade under pressure, or difficulty breathing all mean seek help immediately, whatever the thermometer says.
