Dr. Brown's Options Transition bottle is designed to grow with baby, featuring a removable vent system providing the option of using the bottle with or without the vent. We recommend using the vent system to experience all of the health benefits of the bottle. It helps in reducing feeding issues, aiding digestion, and preserving vitamins. Some parents find removing the vent a convenient option as their baby's feeding becomes more developed.

The Dr. Brown's Transition Bottle is designed to easily convert from Options bottle to sippy spout bottle. Includes a Wide-Neck 240ml Options bottle, level 3 teat and a sippy spout. When baby's ready, simply remove the vent and bottle teat with the super soft transition sippy spout.
