After using the breast pump each time, rinse all utensils that have come in contact with milk with clean water, then scald it with boiling water, and dry it for reuse. Never use disinfectants or detergents with disinfectant ingredients to clean these items, and do not use disinfectant paper towels. "Dry" is the best fungicide. Because breast milk itself is fed with bacteria. If you use sterilized paper towels, etc., sterilized particles will enter the baby's body with the milk, causing damage. You can also buy a large and thin baby bottle cleaning brush. After disassembling the breast pump, use a special bottle cleaner to clean it. After washing, use a pot to boil and disinfect for 10 minutes. Generally, it can be sterilized 1-2 times a day. For mothers who have just given birth, the frequency of breastfeeding is relatively high (usually once every 2-3 hours), but it is not necessary to sterilize after each use. Excessive disinfection and premature aging of accessories can shorten the life of the breast pump. It is recommended to thoroughly clean milk stains and steam disinfection once a day.
