Maikou milk powder and Beinmei milk powder are both big brands, you can choose either one. I chose the milk powder for the baby. It's been six months. I am in good health and sleep well. In fact, the World Health Organization has strict regulations on the ingredients of infant formula, and the ingredients of major brands of milk powder are not very different. Of course, there will be differences between different brands of milk powder, such as Michael. I chose it because it is comprehensive in nutrition, contains all the nutrients that the baby needs, and comes from Denmark. The food testing standards are strict and I feel at ease.
