Nanobébé is the first feeding bottle designed to protect precious breastmilk nutrients which are so essential to baby's health. Thanks to its unique geometry and increased surface area, the bottle cools quickly, reducing bacterial growth and warms quickly at safe temperatures, so you can promptly feed your hungry baby without exposing breastmilk to nutrient-damaging temperatures. In fact, the nanobébé bottle warms up 2-3 times faster than standard bottles. The included breast-pump adaptor means you can express breastmilk directly into the bottle, and then store it in the freezer or fridge. The bottles are stackable which helps track pumping order and saves storage space. Finally, nanobébé's innovative breast-like shape allows your baby to hold it on their own and self-feed from a much younger age.
