Breastfeeding

So FTM here and I really don’t know much about breastfeeding and all the things that come with it (pumping, etc). I am taking a class at the hospital, but it’s not until 11/14 (hopefully baby doesn’t come early). Any books or podcasts or videos that you other mommas found helpful? Literally thinking of buying the Breastfeeding for dummies book 😂🤷🏼‍♀️

A lot of people have said it comes natural, but I’m a worrier and just want to be prepared. Help!!

Also I will be going back to work after 9 weeks so any tips for pumping, keeping up supply while back at work?
