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.

We’re psyched to have them weighing in on everything from colic to cradle cap. www.mdmoms.com
