I used the Brezza for about 1/2 a can. My baby was not gaining weight quick enough during our transition to formula so I tested my Brezza (saw it on TikTok) and found out that for every 2 ounces, the bottle was missing about 1 gram, which is a lot when only ~8 grams are in a 2 ounce bottle. Anyway, I took it apart again and saw that the formula was stuck and gooped up inside the tunnel, even after 1 bottle. I love ByHeart and I love the Baby Brezza so I’m not dissing either product but I don’t really think this formula is made for the machine. With such wholesome ingredients (at least that’s what I assume causes it) it just doesn’t do well like some other formulas do. How I just use my Brezza to dispense the perfect temp water and then hand mix from there :-)

Hi! We’ve been doing tests to try and find the best baby brezza setting, but at this time, we do recommend following the preparation instructions on the can, as we find that ByHeart is made best this way :) (AKA, dissolves easily and mixes smoothly!).
