A: The Dr. Brown's glass bottles and their parts are safe for sterilizing in a pot of boiling water for 3-5 minutes. The silicone sleeve can remain on the glass container during the sterilization, it does not need to be removed. It is best to place the glass in the room temp water and allow it heat up gradually to boiling point to prevent cracking.

A: The internal vent system in Dr. Brown’s bottles is what makes our bottles the best bottle for helping reduce colic, spit-up, burping and gas, preserving nutrients in breast milk and formula, and providing baby a feeding experience much like breastfeeding. Simply put, baby will have the best feeding experience with Dr. Brown’s bottles when using the internal vent system. Baby’s digestive system is usually the last system to fully develop, so it’s important to use the internal vent system until you see improved feeding habits. Here are some signs of improved feeding habits: • They are able to sit up on their own • They have begun some solid food • They are not showing signs of colic, gassiness, or reflux Make sure to speak with your pediatrician before making any changes to your baby’s feeding.

A: Before first use, all parts and bottles are safe for use in dishwasher (top rack only), electric sterilizer, microwave sterilizer, or boiling water.

A: You can leave the silicone sleeve on the bottle when warming. We recommend taking the internal parts out of the bottle and close with a storage cap when warming.
