When it comes to parenting, everyone has an opinion. And while our own moms and friends make some good points now and then, we’re always grateful for expert advice. So here at StrollerTraffic, we’ve teamed up with some of the sharpest minds in the industry to keep us informed on everything from nursery décor trends to vaccine controversies.

As the former in-house nutritionist for both Reebok/LA Sports Club and Exhale Mind Body Spa, Hillary Baron Irwin knows her fruit from her fructose. The fact that she’s also a new mom is the [sugar-free] frosting on our expert cake. www.simplybeautifulmom.com

Ecofabulous founder Zem Joaquin and her team of Earth-loving contributors have found that sweet spot where style meets sustainable. They religiously dish out tasteful tips on Green living, and—lucky for us—have agreed to keep us informed on smart, chic ways to raise kids with eco-flair. www.ecofabulous.com

As the former product demonstrator for Buy Buy Baby, Jamie Grayson knows how to calm a hysterical mom-to-be. These days he customizes baby registries for private clients and has been tapped as a baby-planning expert for the WE channel's "Platinum Babies" series.

We began to worship MD Moms the first time we used their Baby Silk sunscreen wipes. Genius. Since then, we’ve come to realize that doctors JJ Levenstein and Diane Truong are just about the most resourceful pediatricians in the country. We’re psyched to have them weighing in on everything from colic to cradle cap. www.mdmoms.com

As the creator of 30/60/90, Kristi Molinaro can whip any body into wicked shape. We love her understanding of the female figure and her ability to motivate even the most sluggish, postpartum souls to fight their way back into their skinny jeans. www.306090fitness.com

It’s not just the Seedlings Group’s fancy psychology degrees that wowed us—it’s the warm, child-loving approach they take to helping parents cope with everything from sleepless nights and colic to biting and tantrums. Oh, and we thought their website looked really, really nice. www.seedlingsgroup.com

When we heard Heidi Sherman Mitchell brought her 4-week-old baby on a private plane to a press trip in Uruguay, we knew we had to have her as our family travel expert. Heidi is currently the travel editor at Town&Country, and spent many years at Travel & Leisure.
