My little guy doesn't have a strong suck so I've been having to supplement. I pump 30 minutes after each feed for 10-15 minutes. Sometimes I'm drained before the time is up and sometimes I could keep going. Should I continue pumping til I'm drained or should I stop after like 15 minutes? I'm trying to increase my supply in hopes that my little guy will get more from the breast and I can eventually stop pumping...hopefully.
