Six-and-a-half month old babies are breastfed three to four times a day, 200 to 240 ml each time. When the baby develops to six months, not only breastfeeding should be carried out but also food switching, so that the baby will gradually switch from milk as the main food to eating solid-based. According to the infant’s physical growth, neurodevelopment, feeding skills, social skills and other aspects of the development of appropriate to add complementary foods to infants. Supplementary foods should be added according to the principles of from small to large, from fine to coarse, from soft to hard, and from one kind of food to many kinds of food. For 6-month-old infants, pureed foods, such as pureed vegetables and fruits, can be used when adding complementary foods. In addition to this, we should also pay attention to the weight of infants. When infants older than 6 months of age gain an average of 500g per month, it means that they are able to eat enough.
