Frequently Asked Questions
Can I leave the warmer plugged in while it is heating the milk?
Most battery-operated warmers are designed to be cordless during operation. Using them while plugged into a power source can interfere with the internal sensors and might cause the unit to shut down for safety reasons. Stick to charging the device before you head out the door.
Is it safe to heat breast milk in these devices?
Yes, provided you keep the temperature below 40 degrees Celsius. High heat destroys the delicate proteins and antibodies found in breast milk. Using a warmer with an accurate thermostat is much safer than using a microwave, which creates dangerous temperature pockets.
How do I clean the heating chamber?
You should wipe the interior with a damp cloth and a mild, baby-safe soap. Never submerge the entire unit in water, as this will ruin the electronics inside. If you notice mineral buildup, a quick wipe with a little white vinegar will keep the heating plate efficient.
Will these warmers work with glass bottles?
Glass bottles are perfectly fine to use, but they often take longer to heat than plastic versions. Glass is a denser material, so it requires more energy to transfer the heat through the wall of the bottle. Just be patient and double check the temperature before you offer it to your baby.
Do I need to worry about the bottle leaking inside the warmer?
Leaks are a common frustration, so always ensure the bottle collar and nipple are screwed on tightly before inserting the bottle. If a leak does occur, turn the unit off immediately and let it dry completely before attempting to charge or use it again. A little caution goes a long way in protecting your investment.
