Carrie Underwood will appear on "Sesame Street" -- as a worm.

But that's not a bad thing. See, the "American Idol" winner and country music superstar has a muppet of her very own: Carrie Underworm. Underwood performed "Worm Anthem," an original song for the kids show, in which she sings about being "proud to be a worm."

Here is a video preview, in which Carrie Underworm is introduced by none other than NASCAR superstar Jeff Gordon.

As parents and researchers struggle and debate about the cause of the autism epidemic -- or if there's even an epidemic at all -- a new study suggests a link between the disorder and parents' ages.

A study published Feb. 8 in the journal Autism Research concludes that older mothers are more likely than younger ones to have a child with autism. In addition, older fathers significantly contribute to the risk of autism when their partners are under 30.

The New York Times reports researchers analyzed almost five million births in California during the 1990s. Some 12,159 of those children were diagnosed with autism.

According to the Times, previous research concluded that autism diagnoses grew with the age of the father. In this latest study, researchers found when the father was older than 40 and the mother was younger than 30, the autism rate was 59 percent higher than it was for younger men. When the mothers were over 30, that number was about 12 percent.

Here's my husband's brilliant book idea: "The Lazy Dad's Guide to Fun with Kids." It would contain all sorts of games exhausted parents could play without ever getting off the couch. Think: Shoe store. ("Hey kids, I'd like to buy some slippers!") And bus driver. ("Everyone onto the bus!")

Of course, he never got around to writing it -- too tired -- and now our kids are 11 and 13. But it popped into my mind when I talking with a very wise pre-school teacher yesterday who she shared her secret for raising happier, spunkier kids:

"Don't. Entertain. Them."

It was like the Tiddly Winks falling from my eyes. That's it! We have taken on the job of entertaining our kids when it is THEIR job to entertain themselves!

Ads that proclaim "Black Children Are An Endangered Species" are raising eyebrows in Atlanta.

The 65 billboards, one of which is pictured above, are simple -- just that phrase, a large photo of a child's face, and the Web site, TooManyAborted.com.

A hospital in Canada offers some obese children surgery designed to help them lose weight and reduce the risk of type 2 diabetes, heart disease and other potential killers.

The surgery is performed at the Hospital for Sick Children in Toronto. The hospital -- nicknamed SickKids -- is Canada's largest research hospital and one of the largest pediatric academic health science centers in the world.

The Canadian newspaper the Globe and Mail reports physicians at the hospital are the first in Canada to routinely provide obesity surgery to children. The program officially launches this week.

According to the Globe and Mail, it is designed for children ages 12 to 17 with "complex obesity." That means they are overweight because of a medical condition such as a brain tumor.

Super style: Forget the Saints. Or the Colts. Or whoever it was playing in that football game that kept interrupting the million dollar commercials Feb. 7. Fashion watchers and celeb stalkers had their eyes planted firmly on Angelina Jolie, Brad Pitt and their son, Maddox Jolie-Pitt, as they took in Super Bowl XLIV in Miami.

The always stylish trio attended the big game dressed in black -- their go-to color when it comes to everything from the red carpet to the football field. Mom Angelina looked sleek -- and chic -- in black slacks and a black belted trench. Dad Brad was in a black suit -- if only he'd lose that scruffy goatee and beanie he's been wearing everywhere.

And Maddox, 8, showed some New Orleans love by wearing a Saints jersey. Appropriate, since the family has had a home in the Louisiana city for the past few years.

Now, that's winning style.

Sudden infant death syndrome (SIDS) is the leading cause of death for babies ages 1 month to 1 year old. The causes of SIDS are still not fully understood, and while the Back to Sleep campaign has eliminated many deaths, SIDS is still a worry for new parents.

Now, researchers from Children's Hospital Boston say the brain chemical serotonin may be to blame. Serotonin is partly responsible for regulating breathing, blood pressure, heart rate and other involuntary actions as we sleep. According to the researchers, low levels of serotonin may put a baby at risk of SIDS. Normally, serotonin helps babies wake up when they have breathing problems in their sleep, so they can turn their heads and breathe in fresh air. But babies with low serotonin levels may never wake.
