It's the cane! He no longer fought me with the baby when it came to heating the water and making the bottle. I leave the bibe inside hot and only put the powder in the moment. If you don't want everything, I put it back in and after a while it continues to heat up at the same temperature. We should have asked for it before... The only downside is that no more than 50ml bottles enter. Bigger than that, they come out of a window that has the lid (it only has one)
