Once a child develops milk protein allergy, it is recommended that mothers and fathers do not give their children similar milk products, such as yogurt and lactobacillus drinks, because they may contain milk products, including pastries that have milk products added to them. In clinical practice, children who are allergic to milk proteins are also allergic to the proteins in egg whites, and even to the proteins in soy products. Therefore, it is prudent to avoid the intake of egg whites and soy products for children who are allergic to milk proteins. When the child’s constitution has improved over the age of 1 year, or when the allergen has been removed, the child can try a small amount of these foods to see if the allergy will reappear, and if the allergy reappears, the child is not recommended to consume these foods again for a longer period of time. In addition, the proteins in fish and shrimp are also very likely to cause allergies in children, so in the process of eating them, we hope that mothers and fathers can find them in time, and once the child has allergies, then mothers and fathers need to take their children to regular medical institutions in time to avoid delays.
