When a two-month-old baby doesn’t eat milk and keeps crying, the baby’s mouth should be carefully examined to see if there is herpes or inflammation of the throat or thrush, etc. If there is, it is necessary to take the child to the hospital to see a pediatric clinic in time to treat and deal with the cause of the illness. It should also be noted whether the child has a cold, such as intestinal viral or bacterial infections, which can cause digestive symptoms, resulting in decreased appetite and crying during breastfeeding. It should also be noted whether the child has a food allergy, common milk protein allergy, breastfeeding is related to the mother’s diet, if the mother ingests food that the baby is easily allergic to, the baby will cry when breastfeeding, and do not want to eat the milk, the appetite will be reduced. There are also some infants to note whether there are abdominal lesions, such as intestinal obstruction, intussusception and other conditions, because the intestinal tract is not very smooth will not want to eat milk, easy to cry all the time when eating milk.
