Baby Heartbeat Monitor Explained: A UK Buyer's Guide
By Chloe E.2026-06-187 min read

Short answer: A baby heartbeat monitor in this nursery is a wearable sock with a sensor pod, a parent base station and a phone app. It shows live pulse rate, oxygen and sleep. It is a consumer home monitor. It does not replace watching your baby in person or medical care.

What is a baby heartbeat monitor?

Parents often search “baby heartbeat monitor” when they want more than a nursery camera. Some mean a fetal Doppler. Others mean a wearable sock that reads pulse from baby’s foot. This shop sells the second kind: a fabric wrap sock, a round bedside base station, and a companion app.

How does the sock monitor work?

Fit the sensor pod in the mint fabric sock and wrap it on baby’s foot. Plug in the parent base station. Open the companion app for live pulse rate, oxygen and sleep sessions, including wakings. When readings leave the preset range, the base station alerts with light and sound and the app prompts you to check on baby. Sleep history, pulse, oxygen and movement trends stay in the app.

This Mint colourway comes with one fabric sensor sock and one round parent base station.

How does that compare with a camera?

A camera shows you the cot. The wearable sock adds pulse, oxygen and sleep in the app, plus light and sound on the base when readings leave the preset range. Many families use both.

Is it a hospital monitor?

It is a consumer home monitor for pulse, oxygen and sleep. It does not replace in-person checks, NHS safer-sleep advice or medical care. The Lullaby Trust still asks you to put baby on their back in a clear, flat cot.

How do I get started?

  1. Plug in the parent base station.
  2. Fit the sensor pod in the fabric sock.
  3. Wrap the sock on baby’s foot so it sits snug.
  4. Open the companion app for live pulse rate, oxygen and sleep.
  5. Keep the base nearby so you can see and hear alerts.
