Do nipples harden when cooked? First, nipples will harden when cooked many times. There are two reasons for nipple sclerosis. One possibility is that the nipple hardens during scalding with boiling water. Second, because the nipple has aged and hardened after a certain service life. The service life of pacifiers is generally about one or two months. See common pacifiers are divided into silicone and rubber. Silicone nipple is transparent white, which is less prone to aging than rubber nipple, and can generally be used for about two months. Rubber nipple is soft, close to mother's nipple, but rubber nipple has rubber smell, some babies don't like it, and it is easy to age, and its service life is about one month. However, the aging degree of nipples is also related to the frequency of use and disinfection. The more disinfection times, the more frequent use and the faster aging. Therefore, mothers should always check their nipples. If the nipple is discolored, hardened, sticky or deteriorated, it should be replaced with a new one. As for how to choose a pacifier, mothers can choose according to their baby's actual situation.
Second, 1-3-year-old children still need pacifiers, especially 1 year-old children. Mom and dad can't save money in this respect. It is best to disinfect the baby's nipple every day, because it is convenient for the mother to disinfect the nipple. Now that all kinds of steam sterilizers have withdrawn from the market, mothers can buy them reasonably according to the actual situation. If you don't disinfect every day, you should also pay attention to thoroughly cleaning the nipple and accessories after meals. Wash nipples from the inside out. Rinse with clean water. Pay special attention to clean the nipple hole and rinse it with water to ensure that there is no food residue.
What is a nipple? 1. A nipple is a tool used on a bottle to help suck milk, mainly for babies.
2. From the shape, it can be divided into simulated nipple and non-simulated nipple. The simulated nipple is soft, the overall shape of the nipple is full, and the outer side of the nipple head is wavy. When drinking milk, you can remove the tongue coating, which is smooth and easy to clean. Because it is very close to breast milk, it is called a simulated nipple.
3. From the raw materials, it can be divided into: rubber nipple (yellow, sulfur content is easy to exceed the standard), pvc nipple (the high temperature can only reach about 80 degrees Celsius), solid silicone nipple (the high temperature can reach 140 degrees Celsius, and the nipple materials of domestic counterparts are also international counterparts, which meet the international standards of Europe and America, and are transparent and milky white, which is the material used by the first generation of darling bear nipples), and liquid silicone.
4. According to the different openings, it can be divided into round holes, straight holes and cross holes. Now there is a flat nipple on the market, which is more suitable for the baby's mouth shape.
5, the size of the nipple hole can be determined according to the baby's sucking ability. Most pacifiers sold in the market have cross holes. This way of opening is more scientific, and the amount of milk can change according to the baby's sucking strength. However, this nipple is easy to be bitten by the baby and should be replaced in time.
