Read, Read, Read
While books may require a bit more discipline than attending a class, they make up for it with the increased flexibility of fitting into the nooks and crannies of a busy schedule. Either check out the childbirth section at your local library or cruise Amazon reviews until you find titles that call to you. Anything written by Ina May Gaskin, one of the world's most famous midwives, is a great place to start. She normalizes medication-free childbirth with positive birth stories and a ton of fantastic advice.
