The twist adapters for Dr Brown does not work. It doesn’t screw on right to the bag which causes a significant amount of breast milk to leak out. I had no choice but to stop using it and go back to feeding my baby from the bottle. Very disappointed.
Works great, my baby loves the nipple mimics the breast nipple with how slow it is. Used to use a different bottle and he would spit up and be suoer gassy, not a problem anymore and it fits right on my pump so alot less cleaning as well.
