It's been two months that I use these layers. A maternity had layers of prema as my daughter weighed less than 3 kg and standard layers were too great. Since my return home it is these that I use. I breastfeed my daughter, her stools are liquid and have very rarely overflow (instead of to poor positioning of the layer because the miss wriggles a lot!). I am very happy. She now weighs over 4 kg and I still use them because it is tiny. A great product! The premium delivery as well as the subscription proposed by amazon is super interesting. I particularly like to receive the home quickly. With a baby is convenient because it is not so free in his movements.
