These premium MAM baby bottles are crafted from European borosilicate glass that resists shattering, scratches, and stains. The anti-colic nipple reduces gas and discomfort by allowing air to flow freely while your baby drinks, minimizing bubbles so they swallow less air and feed at their own pace. Made with soft, BPA-free silicone that mimics a mother's natural nipple shape, these bottles are ideal for newborns, preemies, and combination feeding. They withstand high temperatures for safe dishwasher cleaning and sterilizing, plus they're thermal shock resistant for refrigerator storage and warming. As your baby grows, these bottles adapt to all MAM nipple sizes and flows, so you won't need to buy new ones. Rigorously tested to meet American and European safety standards, these durable bottles grow with your baby from day one.
