Birthing books?

M • Loving life! ❤️✌️
Does anyone have any suggestions on some good books to read about relaxation techniques during birth? This is our first child but due to work schedules hubby and I most likely won't make it to a birthing class but I would like to at least read up on some meditation and breathing techniques etc...
I know there's Bradley Method books but what else is out there? If it helps with suggestions, I'm not really set in stone about natural birth vs. Epidural, just plan to go with the flow and see what my body is feeling that day 😊
