Patient's question:
Here is the translation of the provided content into English:"Two time periods expressed milk want to put together, two time periods milk can put together?"
Doctor's answer:
Avoid combining milk from two different time periods, as if the usage times are different, you can discard the earlier milk first and still keep the later milk fresh for the next day. It's essential to store them separately and clearly label the date and time. It's best to consume within 2 to 3 hours, and the longest storage time is 12 hours. Prolonged storage can lead to milk spoilage, which may affect the baby's health. Do not give the baby milk that is older than 12 hours.
