Frozen breastmilk can be stored for about three months, and thawed breastmilk must be eaten within 24 hours and not frozen again to avoid bacterial infection, which can easily cause diarrhea and other conditions after the baby eats it. If you can get your child to eat fresh breast milk, you should give your baby regular medical checkups to assess the baby’s development. During the breastfeeding period, the mother should pay attention to strengthening nutrition and having a balanced diet, pay attention to drinking more chicken soup, fish soup, etc. It is also recommended to pay attention to eating more vegetables and fruits, and usually ensure enough sleep to avoid staying up late, being tired and having emotional anxiety, having big mood swings, etc. so as not to cause milk reduction. Strengthen exercise, prevent colds, diarrhea, etc. to reduce the risk of medication during breastfeeding.
