The amount of milk powder brewed is not something we can put at our own discretion, but mainly depends on the needs of the baby’s growth and development, which we can determine according to the baby’s age. Each formula will be marked on the packaging with a clear brewing ratio, which is based on the nutrient content of each brand of milk powder. Generally, it is 1 scoop of milk powder and 30 ml of water, but it depends on the brewing instructions of the various formulas. Here we should also add that the brewing ratio refers to a flat spoon, so as to ensure the accuracy of the brewing concentration, never a full or half spoon at random, to avoid the milk is too thick or too thin. So, we can find that most of the milk powder cans have ad hoc scrapers at the mouth, and need to scrape away each spoonful of excess milk powder. The amount of milk powder eaten by babies at different stages has different requirements: 1, the first few days of life The amount of milk can be calculated according to the weight of the baby per kilogram, 100-200 ml per day, because the milk is not easy to digest, to water, the ratio can be 4:1, 3:1, 3:2, 2:1, 1:1, plus 5-8% sugar, every 3 -3.5 hours, 7-8 times a day. If the baby weighs 3 kg, it needs milk 3 x 100 (120) ml = 300 (360) ml of milk, add water and then divide the total amount by the number of meals, and you can get the amount of milk for each meal. If two parts of milk to one part of water, it is 300 (360) ml of milk + 150 (160) ml of water, the total amount is 450-480 milliliters, divided into 7-8 times, each meal is 60-70 ml. Milk with milk 5% sugar, in five and six months are increased by this ratio. 2.15 days to full moon If the baby digests normally, he can eat pure milk, nearly 100-150 ml per kilogram of body weight, about 60-100 ml per meal. 3.After full-term to two months, the amount of milk will gradually increase according to the weight of the baby, and the baby will be fed 6-7 times a day at an interval of 3.5-4 hours, and will eat about 80-120ml per meal. Up to 150 ml can be eaten. 4.Infant two to three months Feed 5-6 times a day, every four hours, and eat 150-200ml of milk each time. 5.Infants from three to six months Feed 5 times a day, every four hours, and eat 150-200 ml of milk at each meal: 3-5 months, 200-250 ml at 5-6 months, and should master the total amount of milk eaten, which should not exceed 1000 ml per day. The amount of milk per meal should not exceed 250ml. At 4 months of age, you should start feeding your baby supplementary food before breastfeeding. There are 4 kinds of mistakes that can damage the nutrition of milk powder, such as water temperature, brewing order, etc., which can affect the dissolution of milk powder and thus the absorption of the baby. Common mistakes in formula preparation, have you been hit? The first one is to shake the bottle to make the milk powder. When the milk powder is shaken vigorously up and down, a lot of bubbles will be generated, and when the baby drinks the milk with a lot of bubbles, he will swallow the air in the bubbles at the same time, resulting in easy vomiting and bloating after drinking the milk. Correct practice: Clamp the bottle with both palms and roll it back and forth. This way the brewed milk solution will not only allow the milk powder to fully dissolve, but also will not bubble up! Mistake 2: Adding water after adding milk powder first will make the milk too thick, affecting the digestion and absorption of the baby’s gastrointestinal tract, causing indigestion and dry stools, which can seriously cause necrotizing hemorrhagic small intestinal infections. Correct practice: pour a quantitative amount of 40 ℃ ~ 60 ℃ warm boiled water into the bottle, and then add the appropriate proportion of milk powder, it is best to eat now. Mistake 3, the use of mineral water or pure water milk powder mineral water is rich in minerals, phosphate, calcium phosphate too much, and infant gastrointestinal digestive function is not yet sound, long-term use of mineral water milk will trigger infant indigestion and constipation. Pure water loses the mineral elements of ordinary tap water, and the absorption rate of calcium from water can be to more than 90%, so it is also not advisable to use pure water to brew milk. Correct practice: use boiled tap water to brew milk powder. Mistake 4, using boiling water to brew milk powder The water temperature is too high, which will destroy the whey protein in the milk powder to produce clots and affect the digestion and absorption of the child. On the other hand, certain vitamins that are unstable to heat will also be destroyed. Correct: Use lukewarm water, the most suitable temperature for brewing milk is 40 to 50 degrees.
