Can I freeze warm and freeze breastmilk in mōmi bottles?
Yes, both mōmi glass and BPA-free polypropylene bottles can be warmed by placing them in a bottle warmer or warm water. (While the bottles are microwave-safe, baby's bottles should not be warmed in the microwave as this can create hot spots and reduce nutrient quality.) All mōmi bottles are also safe for freezer use. When freezing, be sure to leave space in the bottle to account for milk expansion.

Are mōmi bottles compatible with breast pumps?
all mōmi bottles except for original (5oz) glass can be used with our medela pump adapter set, making it convenient to pump directly into the bottle. These adapters are not compatible with glass mōmi bottles.

Are these bottles compatible with mōmi nipples and other accessories?
Yes, mōmi replacement bottles are compatible with gen 1 and gen 2 bottle accessories and nipples, allowing you to store, warm, and feed from the same bottle.
