When the baby can eat complementary food, parents can try to give the baby boiled soybeans. But soybeans must be cooked thoroughly, so that the baby's stomach can be digested and diarrhea and abdominal pain are not easy to occur. In addition to boiling soybeans, parents can also make soybeans into soy milk for their babies. Moreover, soybeans can also be made into foods such as tofu, bean curd brain and bean skin.

Parents who want to make tofu brains need to prepare soybeans in advance and soak them in water for one night. Then squeeze it into soybean milk and pour it into a pot to cook. When it cools down, you can put a substance that can coagulate soybean milk in it, then cover it and wait for 20 minutes, after which the tofu brain will take shape.
