Breast feeding early…

I want to start breast feeding at 38 weeks pregnant. I know it might start labor, however, I did have my daughter at 38 weeks pregnant and the main reason I want to start early is to get my milk supply started. It wasn’t easy breastfeeding my daughter, the milk wasn’t coming in fast enough and I felt so bad that I wasn’t able to give her enough. I also want to be able to start a milk stash for baby boy as soon as possible. I don’t want to solely breastfeed either, I want to be able to breastfeed and bottle feed my breast milk as well…

What are some thoughts on this topic?

Has anyone started early?
