The correct method of breastfeeding after childbirth can ensure sufficient milk for the child, promote the child’s growth and development, and prevent the mother’s breasts from accumulating milk, which can be sucked out with an electronic breast pump on a regular basis. It is not recommended to use a breast pump immediately after childbirth. It is best to let the child naturally suck milk for a period of time after childbirth and then use it as follows: first wash the electronic breast pump, then wash the nipples, align the breast pump cover with the nipples, squeeze out the air, plug in the power supply and then start the switch to suck milk. Generally, each time you suck breast milk, you have to swap the nipples on both sides, and the amount of milk sucked each time can be about 500ml.
