Our take
Why we like it
A convenient screening tool, but technique and the child’s age matter. A reading is not a diagnosis or a replacement for medical advice.
What parents should know
Seek help for a feverish under-3-month-old at ANY temperature. 38°C or above in a baby under 3 months is urgent: NHS 111 / urgent advice.
Pros
- + Minimal contact
- + Quick to use
- + Useful at 3am
Cons
- − Technique affects results
- − Needs confirmation when concerned
