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 the baby stops sucking to swallow or take a breath, the milk also stops flowing. The special anti-drip design of the teat protects the milk from spilling. The opening of the teat is designed so that the milk flows only when the baby is sucking. This way you can be sure that the milk won't spill anywhere. Choose the right milk flow rate for your baby. Each baby eats differently and at its own pace. When designing the pacifier, we took into account different milk flow rates, so you can successfully find the one that perfectly suits your child's needs and adapt the bottle to his or her individual requirements. All Natural Response pacifiers are made of soft silicone.
