Emily Vanek is not buying up a bunch of LeapPad Explorers herself, but she may be at least partly to blame for some stores selling out of the $99 children's tablet this holiday season.

"The LeapPad is incredible," the Denver mother of three boys wrote to the 6,000 readers of her ColoradoMoms.com blog. "Not only do kids get to have a toy resembling their parents' tablet, it's durable and my favorite part?! It's not just mindless games they are playing."

These days, mommy bloggers don't just gab about spilled milk and poopy diapers. In fact, they've become so influential in the $22 billion toy market that toy makers go to great lengths to get their seal of approval. Their thumbs-up is particularly important during the holiday shopping season when toy makers hope to create the next hit toy.

It's a major shift for toy companies, which have always given out samples of new dolls, games and other playthings to drive sales. Five years ago, they handed out 98 percent of those products to TV stations, newspapers and magazines. But today, as much as 70 percent go to bloggers.

It's hard for toy makers to ignore the monstrous number of mommy bloggers. Nationwide, there are about 4 million or so mommy bloggers who influence millions of other parents.

"Mommy bloggers started because they wanted to share things about a new baby, but the most influential ones got into social media and realized they could make a difference," says Maria Bailey, whose BSM Media firm helps companies pick mommy bloggers with the most reach on the Twitter and Facebook social media websites. "Sometimes that difference is as simple as directing a mom to a toy that will save money."

That's why when LeapFrog Enterprises wanted to roll out its LeapPad Explorer kid-size tablet, it reached out to 200 of the top mommy bloggers. It seems to have paid off. The company declined to give sales numbers, but the LeapPad has been selling out online and in stores across the country this holiday season.
