Babies should add complementary foods no earlier than 4 months, no later than 6 months, 4 to 6 months is a critical period for babies to add complementary foods. If added on time, it can enhance baby’s appetite and develop good eating habits; if added too late, it is easy to form sick habits of anorexia and refusal to eat. Adding complementary foods should follow the principles from less to more, from thin to thick, from one to many, from small to large. From less to more: Each time you add a new food to your baby, you can only feed him once a day, and the amount should not be large. For example, if you add egg yolk, add 1/4 of it at the beginning, after 3~4 days the baby has no adverse reaction, and there is no hunger between meals, normal bowel movement and sound sleep, then increase to half egg yolk, and later gradually increase to the whole egg yolk. From thin to thick from: when babies start to add complementary foods, they have not yet grown teeth, so the mother can only feed the baby liquid food, and then gradually add semi-liquid food, and finally develop to solid food. If you add solid or semi-solid food at the beginning, your baby will definitely have difficulty digesting it, leading to diarrhea. The transition should be gradual according to the development of baby’s digestive tract and the growth of teeth, i.e. from vegetable soup, juice, muddle to rice paste, vegetable puree, fruit puree, meat puree, and then to soft rice, small pieces of vegetables, fruits and meat. In this way, the baby can absorb well, so that indigestion will not occur. One kind to many kinds: Feed only one new food at a time, and add or replace another food after the baby gets used to it. When eating each new food, pay attention to the baby’s stool and skin condition, and stop immediately if there are symptoms such as diarrhea, vomiting, skin flushing or rash, and take the baby to see a doctor to determine the condition. From small to large: food particles should be small and tender, so vegetable puree, fruit puree, steamed egg custard, chicken puree, pig liver puree and other “mud” food is the most suitable, which not only exercises the baby’s swallowing ability, laying the foundation for the gradual transition to solid food, but also allows the baby to familiarize with the natural taste of various foods, and develop a good sense of not The good habits of partial food, not picky eating. Moreover, “puree” contains cellulose, lignin, pectin, etc., can promote intestinal peristalsis, easy to digest. In addition, when the baby is about to grow teeth or is growing teeth, the mother section gradually make the food particles coarse, which is conducive to promoting the growth of baby teeth and exercise their chewing ability!
