Before the milk powder brewing, first of all, we should clarify the milk powder formula equipped with a unified specification of the special spoon, a flat spoon can hold the number of grams of milk powder, and then figure out the number of milliliters of milk powder that should be added to a flat spoon of warm boiled water, and prepare a good 50 ℃ of warm boiled water. When brewing, first pour the right amount of water into the bottle, then pour a reasonable proportion of milk powder into the bottle, and then shake the formula in the bottle well, and then through the nipple like the back of the hands and wrists of adults drop a few drops of milk to judge and determine whether the temperature is appropriate. When the temperature is right, feed the baby. Note: A flat spoon means a natural scooping and scraping, not by shaking and knocking flat, otherwise the concentration of the formula will be high.
