To prepare milk powder for newborns, pay attention to the correct preparation steps and strictly follow the preparation method on each milk powder manual. 1, the new parents should master the steps to brew milk powder: (1) Before brewing milk powder, you should wash your hands clean with hand sanitizer and water. (2) Use the bottle brush to rinse the bottles and other utensils clean. (3) Put the clean bottle, lid and teat into a pot, submerge it in water, cover and boil for 10 minutes, then cool. (4) Boil the drinking water in another kettle and cool to 50°C. (5) Pour the required amount of warm boiled water into the sterilized bottle, referring to the amount used on the package of milk powder. (6) According to the instructions on the package, use the special measuring spoon inside the package to measure the correct amount of milk powder and add it to the bottle. (7) Cover the bottle and gently shake the bottle until the milk powder is completely dissolved. (8) Put a drop of milk on your wrist to test the temperature and feel it is not hot. 2, precautions (1) do not use mineral water to brew milk powder: mineral water is not suitable for infants and children long-term drinking. Because the mineral content of mineral water is relatively high, long-term drinking in large quantities, will increase the burden on the kidneys, increasing the risk of kidney stones. The baby will also have indigestion, loss of appetite and other performance, hindering the absorption of nutrients. It is best to use tap water that has been purified, boiled and cooled to the right temperature. In addition, you can not use rice soup to brew milk powder, because, rice soup has a fat oxidase will destroy the fat-soluble vitamin A in milk powder, not only can not add the two nutrients, but also affect the growth and development of the baby. (2) milk powder should not be too thick: the current whole milk powder or fortified milk powder contain more sodium ions, if not diluted enough will make the baby’s sodium intake increased, increasing its vascular burden, blood pressure, and may even cause capillary rupture bleeding, convulsions, coma and other dangers. (3) Milk powder should be drunk now: some parents put the brewed milk powder in the milk warmer at night and wait until the baby wants to eat milk at night and then take it out, thinking that this is convenient and saves time. In fact, this is not good. Hazards: In a room temperature environment, the brewed milk powder cannot be stored at room temperature for more than 2 hours without being drunk. The temperature in the milk warmer is certainly more than room temperature, so it is easy for the milk powder to deteriorate. If the baby has eaten it, the storage time will be shorter. If there is any leftover milk from brewing, it should be discarded and not eaten again.
