Following the example of nature! The extensive set comes with 2 natural bottles with 125ml each, 2 natural bottles with 260ml each, a bottle and teat brush and a white transparent soother for your little one. The chic bottles have an ergonomic shape which makes them easy to hold and easy to grasp for your little one from every direction. What is special is the  soft and flexible comfort cushion in the unique teat. It supports the natural drinking of your baby just like on your breast. With the Avent Natural bottles, you can combine breastfeeding with bottle feeding and make it easier to transition later on. The innovative petal design of the teat provides more softness and flexibility. The double valve reduces colic and discomfort because the air gets into the bottle and not into the stomach of your baby. Abdominal pain and bloating are thus prevented. With the bottle and teat brush that comes with a curved brush head and ergonomic handle, all bottles, teats and other feeding paraphernalia can be cleaned hygienically.
