Final answer:
The appropriate substitutes for cow's milk for infants who are allergic or intolerant are soy milk and nut milk.
Step-by-step explanation:
Infants who are allergic or intolerant to cow's milk should be given an appropriate substitute. One option is to use soy milk as a substitute. Soy milk is made from soybeans and does not contain the proteins found in cow's milk that can cause allergies. Another option is to use nut milk such as almond milk or cashew milk. These milk substitutes are often fortified with nutrients to ensure that infants receive the necessary nutrition.
