A section of milk powder can be eaten until the baby reaches six months, after the baby enters seven months, it is necessary to feed the baby two sections of milk powder. The reason why baby formula is segmented is because different age groups of babies require different nutrients for growth and development, and different segments of the formula will be enhanced or reduced according to the needs of the baby’s development to suit the needs of the age group of babies. The protein, fat and lactose content of the first segment of milk powder is relatively high, but the content of various mineral nutrients is relatively low, only suitable for the growth and development of babies before six months. The nutrients needed during the growth and development of the baby after six months are not exactly the same as the baby before six months, and need to have enough iron, calcium, zinc and other mineral-based nutrients, which should then be replaced with the baby’s second formula.
