The Dr Brown's Wide Neck Options+ Anti-Colic Baby Bottle Starter Kit includes all of the bottles you'll need to feed your baby from birth to 9 months. The Options venting system is used in the bottles, and it is supposed to prevent colic, burping, and trapped air. It has also been shown to help retain vitamin A, C, and E levels in breast milk by preventing air bubble oxidation. The teat collar's innovative internal vent design allows air to enter the bottle, preventing air bubbles or vacuum development. After that, the air is directed to the sections above the liquid. Because there is no internal suction, the baby may feed more comfortably.
