It depends on whether you’re breastfeeding your baby.
If you’re breastfeeding your baby, but they’re not nursing enough or you’re unable to breastfeed at that particular time, then pumping is a good choice to help relieve breast engorgement.
However, if you’re not breastfeeding, then pumping your breasts may encourage more breast milk production, so it’s best you don’t pump. Engorgement may go away in about 7 to 10 days.
