It's a kettle that has a sensor at the bottom that could stick. I wouldn't boil milk in it. You don't heat milk in a big kettle.

You have to distinguish between warming and boiling. I don't think warming baby milk is a problem, it even works well because you can set the right temperature.

It must be possible.
I only heated water on my trip.

We have used it primarily for milk warming for baby. As long as you don't boil the milk, it should be good.

The interior is made entirely of stainless steel. So there's no problem if the container is cleaned afterwards.

Just found the info myself, please delete question thanks ;).
