After two months of struggling to test many brands of bottles and teats and even bottles of beasts discount store, I am very happy to have tested NUK. Finally! my baby love! Its milk is a little thicker, nipple size M that is supplied is ideal for flow which my baby needs. Very happy with my purchase. I recommend especially if the baby was breastfed and milk flowing on each side of the lips with other brands of bottles and teats.
