The addition of complementary foods for babies is related to their future physical development and nutritional health, and may determine their future eating habits and physical fitness. Adding complementary foods too early or too late is not good for your baby’s health. Adding complementary foods too early can easily cause allergies, diarrhea and other problems, while too late can also affect the normal development of the baby. So when is the best time to add it? What are the instructions for adding complementary foods for babies of different ages? A, 4-8 months of children should still be milk-based diet long-term rice flour fed babies, the body grows slowly, the intake of too much sugar can be stored in the baby’s body and converted into fat, so that the baby looks “white and fat”, but in fact, insufficient nutrition, often accompanied by anemia and rickets, and often due to poor resistance. The infant is often sick due to weak resistance. Therefore, babies aged 4-8 months should still be fed mainly with milk, with a daily milk intake of at least 600-800 ml. On top of that, supplemental foods should be added appropriately. Rice flour is made from rice, which contains 79% carbohydrates, 5.6% protein, 5.1% fat and B vitamins, which are far from enough to meet the needs of infants’ growth and development. If only rice flour-based food is fed in place of milk, due to the lack of protein, not only growth is delayed, affecting the growth of the baby’s nervous system, blood system and muscles, but also low resistance. Second, the baby under 4 months is not advocated to feed rice flour Rice flour is the first kind of food added to the infant’s complementary food, is the excessive food from mud paste food to solid food. Rice flour is easy to digest and absorb, there is no allergenicity, the secretion of pancreatic amylase has a promotional effect, but also facilitate the use of saliva amylase, the heat generated can save the consumption of protein and fat. However, for babies under 4 months old, it is not recommended to feed rice flour because saliva secretion is low and the amylase in it is not yet developed. The process of transition from eating liquid food to regular solid food is very short, from pureed food, to granular food, to basic adultized food that is on the soft side, which is about six months, and this is the baby’s feeding sensitivity period. When trying to give your child new foods, don’t be too conservative, first acknowledge your child’s ability, and then add them scientifically and in a step-by-step manner. Even if there is a period of time not to eat, after a period of time most children can successfully accept. Third, the baby complementary food added learning 4 months before: basic exclusive breastfeeding or formula or mixed feeding; 4-6 months to start: can be gradual, try all kinds of puree complementary food, let the child taste a variety of flavors, of course, allergic babies can postpone the complementary food added time; 6 months to start: can add some granular food, the hardness should be seemingly formed granules or small pieces; 8 to 10 months to try semi-solid foods; after 10 months, solid foods can be eaten. Babies sometimes choke and cough when switching to solid foods; mothers need not be too nervous or even give up this attempt. You have to show your baby more, teach him to eat slowly, chew more, make the food smaller particles and just cook it slightly softer. Fluid – semi-liquid – puree – solid food, this is the baby must go through the feeding training process, there is a time sensitive period, after the corresponding sensitive period, it will cause feeding difficulties and malnutrition of the baby. Baby’s complementary food should not be made into a paste, which will lose a lot of nutrients, and is not conducive to the training of baby chewing function. The nutritional density and breadth of the food (that is, the variety and hardness of the food) should change and increase as the age increases. In particular, do not put supplementary food into bottles for babies to eat, on the one hand, babies eat hard, and easy to cause a little older chewing ability backward, and even swallowing difficulties.
