Since 1956 NUK has been listening to the trusted experts: midwives, doctors, nutritionists and especially mums and dads in order to learn about the needs of both parent and child in those precious early years. NUK Soothers have a specially designed orthodontic shape that adapts to baby’s mouth. This helps to exercise the lips, tongue and facial muscles, which promotes the healthy development of teeth and jaw. The flat shape of the Happy Days soothers helps prevent pressure marks and also stops the soother from falling out of baby’s mouth.  The NUK Air System helps to ensure the mouthpiece remains soft and flexible.  A handy reusable storage case can be used to keep the soothers safe and clean but also to hygienically clean the soothers with steam in the microwave. The soother box can be cleaned hygienically in the microwave oven within 4 minutes. following these instructions: First, fill each side of the box with 20ml water and put in the pacifier. Close the box and heat on 700-1000W for 4 minutes. The steam in this process prepares the pacifier hygienically. Leave the microwave closed for another 5 minutes. Empty out any water remaining. Leave soothers to dry in the open box. To make the instructions more visible, there is a small instruction on the package. The whole and detailed description can be found in the inlay sheet.
