Are dirty diapers and drool the way to bring in the dollars? There's a huge demand out there for these so-called "Momtrepreneurs" who turn messy moments into money.

Most of us know Soleil Moon Frye from her role as TV’s Punky Brewster.

It's been more than two decades since “Punky Brewster” ended, but she's still famous and raking in the cash.

Frye has turned her ordinary routine as a mom of two into big business through her mommy blog.  It's not just the former child star cashing in. 

"It is a lot of work so you have to be passionate about it if you're going to do it," said “Sacramento Sidetracks” blogger Keliah Woodard.

On "Sacramento Sidetracks," you can follow her and her kids' adventures around the Valley. It started when Woodard was looking for things to do with her kids. Parents now read her blog for ideas.

In many ways it's the perfect job.

"It really is in that way. And the fact that it incorporates them is great because it's fun for me and it's fun for them too," said Woodard.

Call it a support group on line. Moms need a place to vent, and to share anecdotes and advice.

"There's a little more trust that comes from another mom over a commercial or advertisement," said Lesley Miller, social media expert and mom blogger.

That's where the advertisers see mommy money.

Within a year of starting her blog “From Dates to Diapers,” companies started approaching Christine Young, a mother of 7, about advertising on her site.    

"I think that's the secret, the key to being a successful mom blogger is just the interaction, the community you create," said Young.

She and her kids go on trips, test toys and products to get reviewed on her blog.

She’s now a spokesperson and ambassador for companies.

While it's turned into a career for Christine, she still craves the connection with other moms.

“What I hope is that ‘Dates to Diapers’ is really a way for moms to be encouraged and they're not in this alone," said Young.

You can expect to make a couple of hundred to several thousand dollars a month.
