Why does my Owlet Sock keep false alarming at night?

What should I do first when any Owlet notification sounds?

Owlet's help article on preventing unnecessary red notifications opens with this line: when receiving a red notification, the very first thing you should do is check on your baby. The Lullaby Trust uses the same order for any monitor alarm. A colour on the base station is not a diagnosis and it is not permission to stay in bed.

1. 1
   Switch off the alarm and go to the baby Look for movement of the chest or tummy. Put your cheek next to the baby's face to feel or hear breath. Talk, blow on or touch their face, or tickle the soles of the feet. Never shake a baby. These are the Lullaby Trust's 'if the monitor alarm sounds' steps (page reviewed 1 February 2025; factsheet updated November 2024).
2. 2
   No response: call 999 Dial 999 at once and put the phone on speaker so the operator can talk you through what to do until help arrives.
3. 3
   Baby responds but you are worried: NHS 111 The Lullaby Trust says to seek medical advice from NHS 111, your midwife, doctor or health visitor if the baby responds or you are worried about their health. In England you can also start at 111.nhs.uk.
4. 4
   Only then look at the app If the baby is clearly breathing and settled, open the Owlet Dream App card. Yellow and red mean different things on the UK/EU help page; they are covered in a separate MayTally guide on yellow versus red.

The Lullaby Trust states there is no research showing monitors help prevent SIDS. A sock reading inside a preset range does not replace an adult in the room for the first six months.

Which everyday things does Owlet list as false-notification causes?

Owlet's Dream Sock: prevent unnecessary red notifications page (dated 2 January 2024, checked 10 September 2026) says that if the event was not an emergency it was probably one of the items below. That is the manufacturer's troubleshooting list. It is not a finding that tonight's alarm was harmless.

How do I check sock fit, cold feet and range?

The UK/EU notifications page says the most common yellow (medium-priority) cause is the wrong sock size, a misplaced sock, or the sock off the foot for at least 60 seconds. Yellow can also mean the sensor was out of range or the signal was blocked for 60 seconds. Owlet asks you to keep the sensor and base station within about 100 feet of each other in US copy; the UK product page says keep the base station within 9 metres of the Dream Sock sensor and never within reach of the cot.

• Fit: sensor windows flat on skin; correct size for the foot. A sock that is only 'nearly' tight is the cause Owlet lists first.
• Kick-off: footed sleepsuits or a regular sock over the Owlet Sock — Owlet says neither blocks the sensor.
• Your body as a shield: do not hold the baby with your back to the base station; tap the base to pause monitoring while you settle them.
• Cold foot: Owlet's own fix is an extra sock over the top. This is a manufacturer tip, not a temperature diagnosis.
• Bluetooth clutter: other radio devices can affect the link; the app shows signal under the sock control hub.

What about night feeds, congestion and periodic breathing?

Owlet tells you that feeds can move oxygen down and pulse up enough to trip a red, and that congestion can make reds more frequent. It also names periodic breathing — pauses of up to 10 seconds — as a newborn pattern. None of those sentences means you skip the check-the-baby step.

The Lullaby Trust factsheet says movement monitors (a different product type) usually alarm after about 20 seconds with no movement, and that even after a long pause most babies respond quickly to touch. If they do not, you are already on the 999 path above.

Owlet's US page says to call a paediatrician if sickness persists. In the UK that maps to NHS 111, your GP, midwife or health visitor — the same list the Lullaby Trust gives after a monitor alarm when the baby does respond.

When should I contact NHS 111 or 999?

• 999 — the baby does not respond to voice or touch, or you cannot see or feel breathing. Speakerphone, stay with the baby.
• NHS 111 / GP / midwife / health visitor — the baby responds but you are worried, they are congested, feeding poorly, or the alarms keep coinciding with illness. Owlet is not the clinician.
• Do not wait for a second red to decide whether to look. Owlet and the Lullaby Trust both put the baby before the app.

In shortCheck the baby, then 999 or 111 as the Lullaby Trust sets out. Only after that use Owlet's list: fit, feed, congestion, pauses, cold feet. A quiet night later is not proof the last alarm was nothing.
