How Long Should I Pump?
It is usually necessary to spend 15 to 20 minutes using the pump, preferably no more than 30 minutes, in order to get a large amount of breast milk. Of course, some mothers may need 30 minutes or more to use a breast pump, especially in the early days.
Also, by emptying the udder more thoroughly, the body will receive an important message to make more milk for the next milking session. If the breasts are not fully emptied or emptied frequently enough, the body will start to produce less milk.
Try to pump at the same times as your baby feeds at home so you can maintain an adequate supply and in line with your baby's needs, usually every three to four hours.
