The NUK Size System provides two different teat sizes with different hole sizes for different foods: Size 1 from 0 to 6 months old and Size 2 from 6 to 18 months old. The hole sizes S, M and L are, in order, ideal for breast milk (and water, tea), formula and puree.
NUK has the right size of teat for every age group and every type of food. For soothers and teats should adapt optimally to the mouth at every stage of life and, with that, to the development of the child’s jaw. Our researchers and developers found out how a child’s palate changes between 0 and 36 months and developed teat sizes for four different age groups.
The four soother sizes only refer to the Genius – it is the first soother with a size for particularly delicate and light newborns from 0 to 2 months old. The 0-6 months, 6-18 months and 18+ months refer to all NUK Soothers.
