Two-year-old children can drink soy milk, especially since some children have milk protein allergies, and normal milk powder drinking can cause blood in the stool and an increase in the number of stools, thus affecting the growth and development of the child. After switching to soy milk, although the quality of protein is reduced, it is very good for the health of children because the protein content in soy milk is also very high, so two-week-old children can drink soy milk. However, if a two-week-old child does not have a milk protein allergy and is comfortable with soy milk, it is better to prefer powdered milk, which is made from cow’s milk and has a more reasonable ratio of nutritional needs for children.
