It’s a blog with a very active podcast feed. Their podcasts are insanely popular on itunes, and no doubt they make a fair bit of money from selling ad space on those podcasts.
I highly recommend the prenatal yoga classes at Birth and Beyond! The instructors are incredibly knowledgeable and supportive, creating a safe and welcoming environment for all expecting mothers. The classes have really helped me stay active, reduce stress, and connect with other moms-to-be.
