Our naturally shaped soft silicone nipples are ideal for babies who have trouble transitioning from nursing to bottle-feeding. Your little one will love to hold onto the skin-like soft and squeezable body that is like no other bottle in the world. And you will fall in love with our wide-neck design for brushless stress-free cleaning bliss! Our bottles are equipped with truly innovative vents that are smartly designed to prevent colic while completely eliminating annoying leaks. They are quite possibly the most thoughtful bottles ever made.
