This bundle includes three 5oz MAM Feel Good premium glass baby bottles perfect for feeding breast milk or formula to newborns and infants. The high-quality, temperature-resistant glass allows bottles to be safely heated, cooled quickly, and sterilized at high temps. The dust caps protect bottles from dirt when not in use. The bottles feature elongated, breast-like silicone nipples designed to facilitate easy switching between breast and bottle feeding to support bonding. Also included are two slow flow level 1 nipples ideal for newborns and two medium flow level 2 nipples suitable for infants 2+ months. Like mom's skin, the BPA-free silicone nipples encourage 94% baby acceptance. Their flat, symmetrical shape fits perfectly into baby's mouth, while the air valve prevents nipple collapse for comfortable pacing. Together, these complementary feeding essentials provide adjustable flow rates to match baby's needs for an easy transition between breast and bottle.
