Infants with allergies usually need to take hydrolyzed milk powder or amino acid milk powder.
If infants are allergic, they will easily be allergic to proteins, especially to the milk proteins in milk powder. If the infant is only mildly allergic, the infant can choose hydrolyzed milk powder, which is a special process to cut the milk protein in the milk powder, easy to be digested and absorbed by the gastrointestinal tract, and is not prone to allergic reactions.
However, some infants are severely allergic and often need to use amino acid milk powder, as opposed to hydrolyzed milk powder, where the milk protein molecules are further broken down.
Infant allergies in the choice of milk powder, must be based on their own situation, and with the gradual growth and development of infants, usually need to gradually transition to ordinary milk powder.
