NOT is Europe's No. 1 best-selling baby products brand, and has been selected as the German standard "Brand of the Century" for its pacifier range. In addition to receiving many awards for design, such as the IF and the Red Dot Award, NOT is also obsessed with the study of product details. The brand's pioneering work, the world's first thumb-shaped artificial pacifier, originated from the meticulous research on infant milk pumping, and has been awarded dental awards by Russia, France, Britain and other countries.
 
Milk production and maintenance are the result of a combination of prolactin (also called prolactin) and the lactation reflex. The baby's sucking stimulates the nipple nerve endings, which transmit signals to the anterior pituitary gland to produce prolactin, which prompts lactating cells to produce milk. Only the baby's frequent sucking stimulation can maintain the level of maternal prolactin and ensure the supply of milk. On the other hand, the nipple has dual tactile receptors for the release of oxytocin and reflex oxytocin, and the baby's sucking can cause the smooth muscle cells around the mammary gland to contract, which is conducive to milk excretion.
 
Based on this principle, NOT has designed soft bumps on the inside of its silicone nipple protector that are scattered around the nipple to massage the breast while the baby is pumping, which not only improves comfort and friction, but also conforms to the breast better, and enhances stimulation and increases milk production. Compared to the butterfly shape of the Lipp Avent, the triangle allows for more optional angles for mother and baby contact, making it easier to use.
 
However, the size of the NOT is on the large side, with the smallest size being M and an inner diameter of 20 mm, which may be difficult to latch on to for newborns and premature babies. At the same time, the ultra-thin texture is also considered by some mothers to be insufficient protection of the injured breast, therefore, the product is more suitable for use in the baby's teething period, which not only adapts to the size of the baby's mouth, but also relieves the friction of the nipple, and the price of 2 pieces is 79 yuan.
 
In addition, NOT comes with a box of nipple protectors, which can be added if there is an air leak or other discomfort when using the nipple protector alone.
