Advice on Postpartum life

I’m only 22 weeks but I’m already thinking about life postpartum. I’m a FTM so basically don’t know what to expect besides things I’ve heard here and there. My coworker said postpartum life was actually hardest for her compared to actual pregnancy and delivery. So for those new mothers out there, what advice do you give and what should I expect in terms of how I’ll be feeling physically, mentally, etc. How can my husband prepare?

And when I say postpartum I’m talking literally the first few weeks.
