The most common reason to use a breast-feeding device during lactation is to keep the milk so that when you are not around, your baby can still eat breast milk. Even when you're with your baby, using a breast pump can help maintain your milk. If you want to continue breastfeeding after work, it is more necessary to suck out the milk and keep it.
In addition, the use of a sucking device can also stimulate milk secretion and increase milk volume. If your baby is premature or can't suck the mother's nipple, using a breast pump to collect milk can not only let the baby eat valuable breast milk, but also relieve the pain and pressure caused by breast inflation. However, it should be noted that the number of milking times when inflating milk should not be too much, otherwise it will make the situation worse.
In special circumstances, if your doctor suggests that you temporarily stop breastfeeding, for example, because you are taking drugs that may be harmful to your baby, or you need short-term hospitalization, then during the period when you can't breastfeed your baby, using a breast pump to suck out the milk can continue to help you maintain sufficient milk secretion.
Although some people prefer to milk by hand, most people still think it will be faster and easier to use a breast pump. At first, you may not be used to it. It's strange to use "machine" to suck out the milk in your breast, but usually it won't take long before you can suck it very easily.
