Mastitis Prevention

Hey guys, I'm preparing for baby number 2. long story short, my first pregnancy I was producing way too much milk, pumping every 20-30 minutes, which resulted in me getting double mastitis to the point of needing hospitalization. I couldn't even pick up my newborn. With a lot of internal debating, I plan on pumping this time. Can I get some pointers or ideas on preventing mastitis? I'm honestly fearful of pumping again but I really would like to try. If it doesn't work out, it doesn't work out. But it doesn't hurt to try. Or maybe it does LOL.
