Question
The child is often suffering from diarrhea while on mixed feeding. The doctor suggests switching to lactose-free formula milk, but the existing brand does not have this type of product. Can you directly switch to another brand of formula milk? What is the method of switching?
Answer
It is recommended to mix the new formula milk with 20% of the original formula milk before switching, and feed the child continuously for three days while observing closely. If there are no adverse reactions, increase the proportion of the new formula milk to 40%, and observe for another three days. If the child recovers normally, you can increase the proportion of the new formula milk to 80%, feed for four to five days, and then observe the situation. If everything is normal, you can then completely switch to the new formula milk.
