This baby bottle bundle includes two complementary sets of bottles to support your baby's feeding and development. The first set contains three 5oz MAM Feel Good premium glass bottles made from high-quality, temperature-resistant glass that can be safely heated, cooled, cleaned, and sterilized. Their elongated silicone nipples facilitate an easy transition between breastfeeding and bottle feeding to support bonding. The second set has three 9oz MAM Easy Start anti-colic bottles with a vented base that significantly reduces colic, gas, and reflux. Their medium-flow silicone nipples also emulate the breastfeeding experience. Both sets are BPA and BPS-free for safety and sustainability. With durable glass and anti-colic vented bottles, this bundle provides versatile, eco-conscious feeding solutions tailored for your baby's changing needs in their first year and beyond.
