Angie Harmon on the best parenting advice she ever got (and then passed on to us)

It's that time of the year when the little people have the sniffles and give them to the rest of us. Advil's solution?

Teaming up with actress Angie Harmon for the Relieve My Fevercampaign, where you can go online to RelieveMyFever.com and enter a video of you and your child, or children, singing the new lyrics to Fever for a chance to win $15,000. The bonus: Children's Advil has teamed up with the Children's Miracle Network Hospitals and will donate $5 for every entry of a video and $1 for every vote, which can help 170 children's hospitals throughout their network and millions of children each year. Translation: You having your American Idol moment can actually help someone feel better.

This week, Shine caught up with Harmon, star of TNT's hit show "Rizzoli & Isles," and mother of three girls.

As part of the "Relieve My Fever contest," you've teamed up with Advil to invite moms and their kids to sing a new rendition of the iconic song, "Fever." On a scale of 1 to 10, 1 being "should only sing to myself in the shower" and 10 being "could easily compete on American Idol," how good is your own singing voice?

A: One. Am I the only one voting, or is it my family? They could think I'm amazing, but they probably don't.

Regardless of talent-we all have that one song we like to sing loud and proud, even if it's in the confines of our car. What's yours?
A: Sweet Home Alabama.

You've said that your series "Rizzoli & Isles" on TNT was literally a wish come true, and that before it came along, you thought you were headed toward retirement. Did you have mixed feelings about the possibility of giving up your acting career for full time motherhood?
A: Well of course, it's giving up your dreams. I'm very very fortunate that I get to do what I love and what I've always want to do since I was a little girl. It's kind of one of those decisions, where it's like do what I want to do or do I do the right thing? And the right thing was go be a mommy and take care of my three little girls. Yeah, it was definitely a wish come true.

What's the most surprising thing to you about motherhood, so far?
A: How smart they are. I was not expecting that. They're intelligent little beings.

What's the best parenting advice you've been given, and who did it come from?
A: Kyra Sedgwick. Keep your heart and your feet in the same place. When my feet are at work, keep my heart at work. When my feet are at home, keep my heart at home. She has very good advice.

We have to ask because we really can't decide from the outside: who's the disciplinarian between you and Jason Sehorn?
A: I'd say it's an even tie.

As we've entered the holidays, Shine's Parenting Gurus (a panel of moms who write about every day life for us) are giving tips on how they stay sane through the holiday frenzy. Some take walks, others have gift wrapping parties and still others opt out of too many parties. What do you do to keep from losing your cool in the end-of-year crush?

A: I don't know, I guess I'm going to have to go to the website and figure out what other mothers are doing because I don't think I have any tips. I did just throw a dinner party for 14 at my house. It was wonderful and fun! Good adult friends all getting together. I kept my girls at the house and it was awesome. I want my girls to grow up with knowing that entertaining is a fun part of life. It doesn't matter if you have a big house or a little house, you can entertain and enjoy time with your friends. I think that's super important, it helps me unwind.
