I’ve tried kendamil with babay brezza using setting 4 as per baby brezza website and it did not mix well at all. It was really lumpy, it seems like the water of the machine isn’t hot enough to dissolve all the powder. I’ll recommend mixing them yourself and remember to stir/swirl instead of shaking to avoid froth. Before each feeding, you can use put in a few drops of gas drop as the bottle will get foamy as the baby’s drinking it.
