The Difrax S-bottle features a valve at the bottom, allowing for a constant air supply from the back of the bottle. This prevents air from mixing with the milk and forming bubbles at the nipple, so your baby swallows less air.
By keeping the air at the back of the S-bottle and preventing it from mixing with the milk, it reduces gas, burping, and spitting up.
Additionally, this ensures that nutrients and vitamins remain intact, as there is no mixing of air and milk.
The S-shape of the bottle allows your baby to feed in a natural, ergonomic position, promoting relaxed drinking and enhancing eye contact between you and your baby.
