Dr Brown’s Natural Flow baby bottles features a patented system with an internal vent designed to create a “vacuum free” environment. This patented internal vent system eliminates the vacuum and air bubbles found in most baby bottles. It allows air to enter through the teat collar, without being incorporated into the breast milk or formula. The air is then channelled through the internal vent system, to the area behind the feed. Babies are able to feed more comfortably because the vent allows babies to feed without fighting the negative effects of a vacuum or the discomfort of ingesting air bubbles. This reduces colic, burping and wind.
