Babies do not eat complementary foods and only drink breast milk, this and improper addition of complementary foods and the mother’s misunderstanding are related. When adding new foods, babies often push out their tongues and even experience nausea, which is a sense of self-protection for babies, while mothers often think it is because babies do not want to accept or do not like to stop feeding. Usually it takes about 10-15 feedings to be accepted by the infant as long as the feeding can be maintained. There is a great deal of individual variation in the infant’s adaptation to food, preference, amount of food eaten, and speed of eating. Generally after an infant becomes familiar with a new food, he still needs to adhere to a certain frequency of eating because there is no food that the infant does not like and the foods that the infant does not like are the ones that he is not familiar with. In this case, it is recommended to eat complementary foods before breast milk every time your baby is hungry, slowly your baby will be able to adapt to complementary foods after several training sessions.
