This vacuum-free feeding method comes closest to breastfeeding, and Dr. Brown's silicone nipples ensure a steady milk flow, allowing the baby to drink at their own pace. The breast-like nipple shape promotes proper latching for a more natural bottle feeding experience and eases the transition from breast to bottle and back. Dr. Brown's internal venting system has been shown to help preserve the nutrients in bottle milk and supports digestion for better sleep. The silicone nipple, along with the internal venting system, provides a reliable and trusted bottle feeding experience, making Dr. Brown's the pediatrician-recommended number one baby bottle in the USA. The bottle is designed to grow with the baby and is suitable for all stages of the baby's feeding journey and is recyclable.

The Dr. Brown's Natural Flow Anti-Colic Options+ baby bottle works best with the built-in venting system but can be removed as the baby develops—there's no need to introduce a different bottle. Dr. Brown's glass bottles are heat and temperature change resistant, capable of withstanding both hot and cold temperatures and gradual temperature fluctuations. Safe for use in the dishwasher (top rack only), in electric sterilizers, and in the microwave or boiling water. BPA-free.
