This innovative bottle effectively and efficiently covers all parents' needs. Dr. Brown's Options grows with the needs of your baby and offers healthy benefits whether your little one is experiencing feeding challenges or not. Options gives you the power of choice. Dr. Browns BPA Free bottle features a patented two piece internal vent system that works unlike any other bottle design. The vent system fully vents our bottle for vacuum free feeding, which we call positive pressure flow, similar to breast feeding. As the baby feeds, air is channelled from the teat collar through the vent system, bypassing the breast milk or formula, to the back of the bottle. Air never mixes with the breast milk or formula which minimises oxidation and helps maintain essential nutrients like vitamins C, A and E. Babies feed more comfortably because the vent system allows them to nurse without fighting the negative effects of a vacuum or the discomfort of ingesting air bubbles. This helps to reduce feeding problems like colic, burping, and wind. The breast milk or formula flows freely, without teat collapse. No vacuum, no bubbles, no teat Collapse! Health Benefits A first of its kind university study to measure nutrient levels in breast milk and formula during a typical 20 minute feeding determined that Dr Brown's fully vented bottles help maintain levels of important nutrients like vitamins C, A & E. Helps maintain vitamins C, A & E: Patented internal vent system is proven to minimize oxidation of breastmilk and formula, to help maintain essential nutrients. Positive pressure feeding: Fully vented bottle design provides vacuum free feeding similar to breast feeding. Helps reduce colic: Vent system eliminates negative pressure and air bubbles to help reduce colic, burping and wind.
