Babies grow to 6 months, you have to start adding supplementary food, so why should we add supplementary food to babies? How to add complementary foods for babies? Why do babies need to add complementary foods? 1, milk feeding can not meet the baby’s energy and various nutrient needs, such as the mother in the late fetal iron stored in the liver has been used up, need food to supplement iron and other nutrients. As the infant grows up and becomes more active, milk as a fluid does not meet the energy needs of the larger infant. And to prepare for weaning from breast milk in the future. 2. 6-month-old infants have the ability to digest and absorb complementary foods. As the digestive system matures, milk teeth begin to erupt, the mouth has the ability to bite, chew and swallow non-liquid food, neuromuscular coordination continues to develop; infants have the ability to appreciate different colors, shapes and flavors of food; gastrointestinal digestion and absorption ability soon increases, and the excretory ability of the kidneys improves, gradually having the ability to digest and absorb complementary foods. 3, conducive to the development of language, communication skills and the cultivation of good eating behavior. When parents feed, it is also an important time for parents and children to communicate with each other, which plays a great role in promoting infants’ intellectual and emotional psychological development. The opportunity to exercise the baby’s oral muscles and tongue movements is an important process for future language development and the development of good eating behaviors. What kind of complementary foods do babies need to add? How to add it? First of all, we should emphasize the principle of adding complementary foods: from one to many, from less to more, from thin to thick, from fine to coarse, add gradually, never too fast. 6 months old baby first add iron-containing rice flour. Feed before eating milk, one flat spoonful of rice flour, mix it with warm water to make a thin burst, feed it with a small spoon, press the lower lip to the tongue and let the baby slowly experience the new way of eating. Mothers feed and show their babies how to chew to teach them how to eat. If the baby digests well and has normal stools, the amount of rice flour can be increased at intervals of 3-5 days, gradually increasing. If you have diarrhea and more food residue in the stool, you can maintain the original amount and reduce the amount or even suspend the supplement as appropriate. Rice flour added about 10 days, you can add vegetable puree. At first, you can use root vegetables, for example, carrot puree, pumpkin puree, pea puree can be. Each kind of addition should be observed for 3 to 5 days to see if there are any allergies. Then add fruit puree. Use a small spoon to scrape the apple into a puree. You can feed them once between feedings. If your baby is allergic to apples, then eat steamed or boiled apples and a little less mashed banana, depending on your baby’s digestive ability. It is better to add vegetable puree first, then fruit puree. Because fruit is sweeter, babies will prefer it, so once babies develop a preference for fruit, it will be difficult for them to be interested in vegetables. Many parents, add egg yolks to their babies first. Because some babies are prone to allergies, egg yolk is a heterogeneous protein and the baby’s intestinal immune function is not yet mature enough to lead to eczema and allergic diarrhea. Therefore, it is now recommended to start feeding after 7 months of age. Please note that the amount of milk should not be reduced while adding complementary foods (800~1000ml per day), otherwise, the weight gain will be slowed down.
