Our award-winning Breastmilk Bottle (150 ml) is the first and only baby bottle designed to preserve the essential nutrients found in breast milk, making it the best bottle for breastfed babies. The innovative design quickly cools breast milk during storage to prevent bacterial growth. When thawing, the Breastmilk Bottle safely and evenly warms 2x faster than other bottles to protect nutrients and quickly feed your hungry little one. Shaped like mom for a natural feel, this bottle feeding experience is second only to direct breastfeeding. The instinctual connection prevents nipple confusion, easing the transition from breast to bottle. For all-in-one feeding convenience, moms can pump breast milk directly into the Breastmilk Bottle and then store, warm, and feed - all with the same bottle. The advanced 360 anti-colic nipple is triple vented to prevent air bubbles and eliminate baby gas, fussiness, and discomfort. These bottles are stackable to save space, and have minimal parts for easy cleaning. As babys health is of utmost importance, our bottles are free of BPA, PVC, lead, and phthalates.
