How It Works

A Warm Bottle in 30 Seconds

The Mavi Baby routine — every time.

Pouring boiling water from kettle into Mavi Baby Thermos to prepare a bottle

01. Fill & Pour

Pour 300ml of freshly boiled water into your Mavi Baby Thermos, followed by 450ml of cooled, sterilised (previously boiled) water. Secure the lid tightly.

Checking the Mavi Baby Thermos smart temperature display showing 40°C — green light confirms safe feeding temperature

02. Seal & Check

Once lid is sealed tightly, turn the bottle upside down and hold for 10 seconds while the lid reads the water temperature. This also confirms the bottle is securely sealed and leak free.

Blue Light — Too Cool (Below 30°C): Water is below the recommended formula preparation temperature.

Green Light — Safe to Feed (30–45°C): Water is within the recommended temperature range for preparing your baby's bottle.

Red Light — Too Hot (Above 45°C): Allow the water to cool before preparing or feeding.
