How old can a child drink plain milk

It is generally recommended that children drink plain milk after the age of 1 year.
It is recommended that children be given plain milk after they reach 1 year of age, as long as a balanced complementary diet is ensured.
The intestines and stomach of children under 1 year of age are not yet fully developed. Milk contains high concentrations of electrolytes and casein, which cannot be digested and absorbed by children before 1 year of age. Moreover, the trace elements contained in cow’s milk are different from breast milk, which does not ensure the child’s nutritional supplementation.
After breastfeeding, you should choose a formula that is more similar in composition to breast milk. The formula adjusts the nutritional structure and contains components essential for the child’s growth and development, which is more favorable to the child’s health. When the child reaches the age of 1 year, you can choose to pasteurize the whole milk after pure milk.
When you give your child pure milk for the first time, you should pay attention to observe whether your child has any uncomfortable reaction, if there is discomfort, you should stop giving your child pure milk, and it is best to consult a doctor.
