Baby complementary food can't be added a lot at once. You need to eat it with milk and gradually add it in the same way to avoid the baby's allergic problem. You can find allergens in time and stop eating in time. When the baby is older, you can try feeding again. This is because the process of starch digestion and absorption starts from the mouth. Our saliva (baby's) contains salivary amylase, which can decompose starch in the mouth, and it is easier to absorb it by adding complementary food from starch-rich food.
In the early stage of baby's complementary food, complementary food is mainly to make the baby adapt to various foods, and the nutrition mainly comes from milk. In the later stage, we should pay attention to the balanced and diverse diet and pay attention to collocation. There is no best food, only better collocation. Because the baby's digestive ability is still weak, when adding complementary food to the baby for the first time, it must be in the order from less to more, one to more, and from thin to thick.
Babies over 6 months generally eat rice flour as a complementary food, but they can also eat egg soup, vegetable puree, fruit puree, meat puree, liver puree and so on. Be sure to mash the food to help the baby digest, and feed it less at first, otherwise the baby will have indigestion, flatulence and diarrhea. After drinking the vegetable juice, put it in his small pot and boil it, then add a little bit to the rice noodles. I usually give him spinach juice. Later, I will cook spinach with water, then take it out and heat it to juice, so I can make rice noodles directly. You can add some avocado to the rice noodles, which is especially fragrant.
