As your baby grows older, by the time he or she is 4-6 months old, he or she will start to drink less milk and have a poor appetite, which is often referred to as “milk aversion”. I often hear mothers of babies in this age group complain that their babies are reluctant to eat milk, that they have significantly less milk to eat, and that they have difficulty feeding their babies. This is due to the fact that babies have been drinking the same kind of food every day since birth, and after a period of time, they may develop an aversion to drinking milk, which is called “milk aversion”. Babies with “milk aversion” caused by this phenomenon often have normal growth and development and good vitality, and their appetite is only slightly poor and the amount of milk is temporarily reduced. Usually, the appetite will be restored naturally in about a month. You don’t have to worry too much about it. But this is also the baby is reminding parents that it is time to give him something different to eat. The best time to start adding complementary foods is 4 to 6 months after birth. As the baby grows up, after 4 months the baby’s exclusive breastfeeding can no longer meet its growth and development: 1, do not like to eat pacifier This is the most common reason, most of the breastfed babies will encounter this problem, because the taste of the pacifier and the taste of the mother’s nipple is completely different. While we feed our babies contentedly, we often don’t anticipate that it is so difficult to get him to accept a pacifier. 2, do not like the taste of formula Babies are used to the fresh and light breast milk, and the taste of formula is different from breast milk, some with a little milk smell, sensitive babies can not quickly adapt to, and therefore refuse to eat. 3.Incorrect feeding method Because of the improper angle of the bottle, it presses to the tongue, so that the baby can’t drink milk. 4.Distracted attention Some curious babies will stop sucking as long as there are noises or people walking around. 5.Pathological anorexia: Acute infection: Your baby has an acute respiratory infection, which leads to nasal congestion and inability to change air when sucking milk. Acute laryngitis and mouth ulcers, which cause pain in the mouth and make the baby eat less suddenly. Babies with enteritis will also eat significantly less milk. In addition, milk aversion can also be a symptom of a serious infection, especially in babies with sepsis, who often have a significant decrease in milk consumption. The baby may be irritable or lethargic, inactive, short of breath or wheezing, and may have a fever or lower than normal temperature, a sharp decrease in milk supply or vomiting or bloating.
