The NUK Signature Soother is modelled on the shape of a mother?s nipple as she breastfeeds, promoting healthy oral development. This NUK dummy is also flat, thin and narrow, fitting perfectly into little mouths and leaving the tongue enough space for natural sucking movements. 100% of orthodontists recognise that this is the right shape and confirm that NUK Soothers do not cause crooked teeth or jaw misalignment.* Available in a range of sweet designs. These glow-in-the-dark designs are not only fun but can help little ones find their dummy if they want it when they wake. *Independent market research; 50 orthodontists, 50 paediatricians, 50 midwives; Germany 2017
