The baby is allergic to milk protein, and the mother can drink crucian carp soup. There's nothing wrong with that. Because drinking crucian carp soup will not aggravate the baby's protein allergy, so don't worry about it, you can drink some appropriately.

However, it should be noted that because the baby is allergic to milk protein, try not to drink milk, eat foods rich in high protein and try not to eat dairy products. This is not a big problem.
