I have a friend who is an exclusive pumper, but she pumps for 40-45 minutes each time!! She has a CRAZY stash though - her entire freezer is filled with frozen milk from top to bottom.

I've always just pumped for 20-30 minutes but wondering if it'll make a difference if I increase it. I just feel like I don't get much more after the 20-minute mark so I don't know if it's worth spending double the time pumping.

How long do you spend pumping?
