Wanting to prepare

I’m currently pregnant with my second. I tried to pump with my first but was in so much pain from the cramping I stopped. I was a single mom so my parents came up every weekend but I was alone most of the time. I really want to pump/breastfeed this one. Any suggestions on how to keep going? Things I need to stock up on now? Tips to not cramp so bad in the hospital every time I pump?
