Sucking not only ensures the intake of food, it also promotes the development of the most varied of abilities. For this, the tongue has to have enough space for free sucking movements. This is the only way to exercise every muscle that babies need for swallowing, chewing and learning to speak correctly. And it is possible with the new NUK Soother: being so flat, thin and narrow, it leaves the tongue enough room. And it fits optimally into the mouth, when the baby sucks it. That is confirmed by midwives, paediatricians and orthodontists*.
