Support for the baby's natural sucking rhythm. Thanks to the responsive Natural Teat, milk flows only when the baby is actively sucking. During a break or swallowing, food does not flow on its own. The baby drinks, swallows and breathes completely naturally, just as if it were suckling the breast. Thanks to this, we avoid spilling the milk and combining natural and bottle feeding becomes much easier. Milk is released only when the child is actively sucking. The innovative design of the responsive Natural teat - the J slit slit allows the child to independently control the pace and rhythm of sucking. Milk is only released when the baby is actively suckling. When your baby stops sucking to swallow or take a breath, the milk also stops flowing. Natural latch thanks to the breast-shaped teat. The wide, soft and flexible teat mimics the shape and texture of a woman's breast, helping your baby latch on and drink calmly. Designed to reduce colic and discomfort. Anti-colic valve keeps air away from your baby's tummy during feeding, reducing colic and discomfort.
