How long each pumping session should last depends on many factors including how long it's been since the last pumping or breastfeeding session, the amount of your milk supply, the size of your storage capacity, and the time of day. But in general they should last between 15-20 minutes. If you're finding that it's taking much longer than that, something probably isn't right.
