The trusted and well-known Difrax anti-colic baby bottle with a green bottom and cap. The S-shape and the valve at the bottom of the bottle prevent air bubbles from forming in the bottle. And that reduces intestinal cramps in your baby. Because food and air are not mixed together, the vitamins and important nutrients are preserved. In addition, the valve ensures that the bottle does not create a vacuum. The bottle has a soft bottle teat with a soft coating for extra grip. The bottle can be used from birth and is easily accepted. You can unscrew the bottom to clean the bottle and, for example, fill it with ice cubes of breast milk. Note: Before each use, check whether the air hole in the center of the valve is open by squeezing it several times.
