The bébémarc Silicone Breast Pump & Antibacterial Feeding Set offers a convenient way for mothers to express, store, and feed breastmilk using the same silicone bottle. The pump uses natural suction for manual expression, eliminating the need for cords, making it lightweight and portable. The set includes a slow-flow, platinum silicone feeding nipple designed with a gradual slope to resemble a human nipple, helping babies avoid nipple confusion when transitioning between breast and bottle feeding.
