When you hear "birthing expert" or "doula," you picture a woman. But what would you think if 'she' was a 'he?' Meet the Doula dude who helps not just the mom-to-be, but the dad-to-be as well.

Welcome to the rocking dad’s class. An introduction to the birthing experience, taught by Brian Salmon.

“I’m the birth guy,” said Salmon.

That’s right, 46-year-old Brian Salmon is a birthing expert, known as a doula. He's a man in a woman’s world, and it brings up a lot of questions.

“The biggest one is, 'Oh my god why would a woman want a male doula at their birth,'” said Salmon.

But many do. Brian’s classes are packed, and one main reason begins long before the delivery room. He helps dads get ready for their child’s birth in the rocking dads class.

"What happens is, the baby is going to come out with a onesie on just like this, no just kidding,” said Salmon.

His sense of humor helps put these soon-to-be dads at ease. That and the fact that this birthing expert is a guy.

“I think he’s a likable dude, and really brings a lot of comfort to the subject,” said expectant dad Eyal Avnon.

His information is solid knowledge. Brian has studied biochemistry, physiology and has a degree in radiology. One topic he teaches dads is the benefits of breastfeeding.

“The baby is getting antigens from mom, it prevents breast cancer, certain types of breast cancer in mom, certain types of uterine cancer in mom,” said Salmon.

Clint Belew is a graduate of Brian’s rocking dads class.

“I tell all my friends, you know, anybody that’s having a baby coming up, I’m going 'hey you gotta go and see this guy cuz he’s gonna change your whole experience,'” said Belew.

Puget Sound's Bastyr College has had men complete certification in their Doula course, and Swedish Hospital's Midwifery clinic has a male doula on staff.

You can find Brian's 'Birth Guy' videos online, along with a lot of other information.
