There are two main methods of transferring milk for babies, including mixing old and new milk and transferring milk every other time, and the steps are different for different methods, as follows. 1. New and old mixed milk transfer method: the new milk powder and the original milk powder mixed drinking, that is, in the old milk powder in the appropriate addition of new milk powder, the amount of small to large, slowly and appropriately increase the proportion, until the complete replacement. For example, first add 1/3 of the new milk powder in the old milk powder for 2~3 days, if there is no symptom of maladjustment (such as abnormal stools, abdominal pain), then take the old milk powder and the new milk powder 1/2 mixed drink for 2~3 days, and then take 1/3 of the old milk powder and 2/3 of the new milk powder mixed drink for 2~3 days, and finally the transition to the new milk powder to replace the old milk powder, that is, to complete the process of transferring milk. 2. alternate milk transfer method: in the beginning of the first 1-3 days of milk transfer, you can add a new milk powder to the baby every day, if the baby does not have abnormal stools or abdominal pain and other symptoms of maladjustment, you can add two new milk powder in the 4th-6th day to the 7th-9th day you can add three new milk powder, and gradually increase the number of times the new milk powder is added, until every meal is transferred to a new milk powder. Milk transfer should pay attention to the principle of gradual and orderly, small meals, not too frequent milk transfer, so as not to increase the burden on the baby’s intestines and stomach. Parents can also consult a doctor or a childcare worker at the local Maternal and Child Health Center about the steps to be taken in transferring milk for babies.
