The Philips Avent SCF690/693 natural bottle range is ideal for mothers who combine breast and bottle feeding. The naturally shaped teat with petal design is particularly soft and flexible at the same time, so that the teat does not collapse. The innovative twin-valve system prevents colic. The bottles have a slightly curved design, making them more intuitive to hold for both mother and baby, while their wide necks make them easier to fill and clean.
