It calls itself “classifieds for moms.” HandMeDowns.com, only a few weeks old, is a classifieds aggregator where parents can buy, sell and give away the toys, clothes and strollers that their kids too quickly outgrow.

It scrapes listings and images from popular sites – including Craigslist, EBay and EBay’s Kijiji – for “gently used” items, and includes on the right rail of search results a “Shop New” box of relevant results from Amazon.com.

It’s the way we’d run Walmart’s beta classifieds site with Oodle, if we ran Walmart.

There’s social consciousness here, too – beyond the recycling of goods: a channel for donating to charity, an area for safety-recall notices, discussion groups and the “Mom Police” – a community-based system for flagging inappropriate content.

Sellers can upload listings for free, of course, into categories that include high chairs, infant swings, maternity clothes, diaper bags, toddler clothing and household baby-proofing items. If sellers post a photo, a pink heart is automatically superimposed on used items and a gold star is superimposed on new items. If an item was indexed from another site,the name of the site is superimposed on the item’s photo.

There are also active categories for childcare – from nannies, babysitters to au pairs – and other services including parenting classes.

Users can sort search results by posting date and by price.

As these start-ups often go, it was founded on one person’s need and time constraints. CEO Norah Weinstein, a Los Angeles attorney who also founded The Hollywood Reporter, said she was frustrated in her searches online for items for her 14-month-old daughter. “The classified sites that were available had some great listings, but were not designed with parents in mind,” she said. “Moms are too busy to sift through thousands of listings to find the items they need, especially those in good enough condition for their children. Our goal is to raise the bar for baby and kids classifieds.”

“Handmedowns.com helps parents save time and money by pulling together all of the products they need into a safe, simple, user-friendly environment,” said co-founder Jane Buckingham, trends forecaster and author of Modern Girls Guide to Motherhood. She was recently named to Elle magazine’s “25 Most Influential Women in Hollywood.”

What isn’t obvious in the site’s debut is how it intends to make money. So we asked. In a few weeks, the site will roll out upsells for priority listings, as most aggregators do.

Launched earlier in November, Handmedowns.com is already serving 20 U.S. markets: Atlanta, Austin, Boston, Chicago, Dallas, Denver, Houston, Los Angeles, Miami, New York, Orange County, Minneapolis, Philadelphia, Phoenix, Portland, San Diego, San Francisco, Seattle, Tampa, and Washington, D.C.
