1. Have appropriate suction;
2. There is no pain in the nipple when used;
3, can finely adjust the drinking pressure.
Under normal circumstances, the sucking pressure of the baby is 60-100mmHg, but since the sucking is not a simple drawing of the nipple, it is not necessary to select a breast pump with strong suction.
Choosing the right breast pump for you depends on how often you plan to use it and how much time you can spend on breastfeeding. If you are working full time and need to sneak out your time to suck up your breasts, then you need to use a fully automatic breast pump because it can suck the milk from both sides of the breast at the same time. However, if you only need to suck out some milk occasionally so that others can help feed your baby when you are out, then you only need to buy a cheap manual breast pump.
Manual breast pump is better. The breast pump is divided into manual type and electric type. Some people may feel that electric is better in order to save trouble. In fact, this is a wrong statement, because each mother's mammary gland will have individual differences. Electric is a set speed. If used improperly, it is likely to cause mammary gland. Pain, so the breast pump is still better to choose manual, because the manual type can adjust the speed according to the individual's own needs.
