Marcus & Marcus Silicone Angled Feeding Bottle & Breast Pump gives mothers an easy and convenient way to express breast milk as they may store and feed a baby with the same silicone bottle. Marcus & Marcus Silicone Breast Pump has the power of natural suction, providing a comfortable way for mothers to express breast milk manually. Unlike the electric breast pump, our breast pump does not require any cords. Instead, it is lightweight and portable to carry. The set comes with a slow flow, platinum silicone feeding nipple. The extra soft feeding nipple is designed in a gradual slope shape which is similar to a human-like nipple that helps babies to prevent nipple confusion when switching between breast and bottle feeding. When breast milk is not used right away, simply store the bottle in the fridge with the provided sealing disc. The silicone bottle is designed with an angle which helps promote a semi-upright feeding position benefiting babies from gas, colic, fuss and spit-ups. The feeding bottle has 3 volumetric markings for parents to read the remaining milk without unlatching. The whole set is made with BPA, PVC, and Phthalate free material to ensure the best and safest quality for storing the most precious breast milk.
