Preparing for breastfeeding

Samantha • I'm pregnant with my second child and we are having a baby girl out 4 year old son is so excited to be a big brother!!!
I'm 30 weeks along with my second baby and I had a really hard time breastfeeding with my first and I'm determined to do better with this one. I'm wondering if there are any ways to prepare my nipples or help produce milk more? Any information will help please, thank you in advance
