The most common reason to use a breast pump during lactation is to preserve milk so that your baby can still get breast milk when you are away. Even when you are with your baby, using a breast pump can help maintain your milk supply. If you want to insist on breastfeeding after work, it is even more necessary to save the milk. Using a breast pump can also stimulate milk secretion and increase milk production. If your baby is premature or can't suck mother's nipples, using a breast pump to collect milk not only allows your baby to eat precious breast milk, but also relieves the pain and pressure caused by the expansion of milk. But I need to remind you that you should not express too many milking times during expansion, otherwise it will make the situation worse.
Under special circumstances, if your doctor advises you to stop breastfeeding temporarily, for example because you are taking drugs that may be harmful to your baby, or you need short-term hospitalization, then use breastfeeding during this period of time when you cannot breastfeed your baby. The breast milk can continue to help you maintain adequate milk production. Although some people prefer to express milk by hand, most people still feel that using a breast pump is faster and easier. At the beginning, you may not get used to it, and it feels a bit strange to use a "machine" to suck the milk out of your breasts, but usually it doesn't take long before you can suck it smoothly.
Breast pumps can be divided into two types: electric and manual. If you are using an electric breast pump, just buckle the cup on your breast and turn on the machine, and it will automatically suck your milk into the connected container. The manual breast pump also uses the cup, but you have to manually squeeze it!
