Generally speaking, the conversion of one type of diarrhea milk powder to another type of diarrhea milk powder is also necessary because if one type of diarrhea milk powder is suddenly and completely converted to another type of diarrhea milk powder, it will often cause the child’s intestinal tract to not adapt, thus causing the child’s diarrhea symptoms to worsen and even cause the child to vomit. When switching to another formula for children, you can use the principle of gradual change, for example, you can first switch to 1/3 of another formula, and then switch to 1/2, 2/3 and then completely to another diarrhea formula, which is mostly acceptable to children’s intestines.
