Sleep through fever nights. P20 does the watching.
A 2g sensor under the arm records every 5 seconds while your child sleeps — and wakes you only at the exact moment the fever crosses your alert threshold.
Why a baby fever monitor beats checking every two hours
Parents check every hour or two with an ear thermometer, waking the child each time — and still miss the 2am spike. By morning, all the doctor gets is a guess.
- Manual checks wake a sick child who needs rest
- Spikes between checks go unnoticed for hours
- "It felt high around 2am" is all the paediatrician has to work with
Continuous fever monitoring for babies: how P20 works at night
Alerts only when it matters
Set a threshold like 38.5°C. P20 stays silent until that exact moment, then your phone buzzes — no hourly wake-ups, no guessing.
Kick-blanket detection
When a feverish child kicks off the blanket, temperature drops sharply. P20 recognises the pattern and alerts you before the child gets chilled.
A full curve for the doctor
Every reading from the whole night, in one exportable graph. Doctors adjust treatment based on the trend, not a single number.

How to choose a continuous thermometer for your baby
What makes a baby fever monitor different from a regular thermometer
A standard ear or forehead thermometer answers one question at one moment; a baby fever monitor is designed to stay on and keep answering that question all night. P20 is worn under the arm on a hypoallergenic patch and samples every 5 seconds, so instead of a single number you get a continuous curve showing when a fever started, how fast it is rising, and whether it is responding to medicine. For overnight fever monitoring, that continuity is the entire point — a spot-check thermometer cannot tell you what happened at 2am unless someone was awake to check.
How to monitor baby fever at night without losing sleep
The practical problem with manual checks is that they wake the child to get an answer, and still leave hours of blind time in between. A wearable baby temperature monitor removes both problems: it measures continuously without disturbing sleep, and it only notifies a caregiver when the temperature actually crosses a threshold they set themselves. With P20, that means opening the app once at bedtime to set an alert — for example 38.5°C — and then sleeping until either the alert fires or morning comes, whichever is first.
Kick-blanket detection and why it matters for infants
Infants and toddlers cannot reliably self-regulate temperature, and a feverish child who kicks off their blanket can cool quickly and then spike again as they warm back up. P20's kick-blanket detection recognises this specific drop-then-rebound pattern in the temperature curve and alerts the caregiver, rather than treating it as a fever breaking. This is a pattern manual spot-checks essentially never catch, because it requires continuous data to see the shape of it at all.
Safety considerations for continuous wear on a baby
Any device worn continuously on an infant needs to clear a higher safety bar than one used for a thirty-second reading. P20 weighs 2 grams, uses a hypoallergenic medical-grade skin patch rated for continuous wear, and is a registered Class II medical device with clinically validated ±0.2°C accuracy. There is nothing inserted into the ear and no glass or mercury — the sensor sits externally under the arm, which is why it is suitable for newborns as well as older children.
Baby fever monitor questions parents ask
Is a wearable baby fever monitor accurate enough to trust overnight?
P20 is a Class II medical device with clinically validated ±0.2°C accuracy — comparable to a good clinical thermometer — but measured continuously rather than once. Continuous sampling also avoids the placement inconsistency that affects single ear or forehead readings, so overnight trend data is generally more reliable than isolated manual checks.
At what age can a baby start using a continuous temperature monitor?
The hypoallergenic patch is designed for continuous wear on sensitive skin, including newborns. As with any wearable health device, parents should check placement doesn't irritate the skin and consult their paediatrician for guidance specific to premature or medically fragile infants.
How do I set a fever alert threshold for my child?
In the P20 companion app, you choose the exact temperature that should trigger a notification — commonly 38.0–38.5°C for children, though your paediatrician may recommend a different threshold. The app stays silent below that number and alerts immediately once it's crossed.
Can I share my baby's temperature readings with my partner or a grandparent?
Yes. The companion app supports family sharing, so multiple phones can watch the same sensor's live readings and receive the same alerts simultaneously — useful for a working parent, a co-parent elsewhere, or a grandparent helping with childcare.
What happens to the data after the fever passes — can I show it to a doctor?
The full night's temperature curve stays available in the app and can be exported. Rather than describing a fever from memory, parents can show the paediatrician the exact onset time, peak, and how it responded to any medication given.
