I’ve been there. Your baby outgrows an outfit before you feel like they’ve even had a chance to wear it, so you toss it into a storage bin “just in case.” Then another bin fills up, and another. Before long, the closet is packed with tiny socks, sleepers, jackets, and clothes that no longer fit.
Baby clothes can be surprisingly hard to let go of because so many pieces are tied to memories. For a while, I would either pass them along to family and friends or drop bags off at Goodwill. But after seeing how much some barely worn clothes could sell for, I started looking at those overflowing bins a little differently.
If you’re already clearing out your home, selling some of those clothes can put a little money back in your pocket. You don’t have to sell every single onesie individually, either. Depending on what you have, there are several easy ways to turn outgrown baby clothes into extra cash.

Facebook Marketplace
Facebook Marketplace is a convenient choice if you want to sell locally and skip shipping. It works especially well for bundles since parents often prefer buying a whole set of clothes in the next size rather than hunting down individual pieces.
Take clear photos, mention the sizes and brands, and be honest about the condition. Grouping clothes by size or season can also make your listing easier for buyers to shop.
Once Upon A Child
Once Upon A Child is a popular option for parents who would rather sell clothes in person. You bring in your gently used baby and children’s clothing, and the store decides which items it wants to purchase.
You probably won’t get as much as you might from selling desirable pieces individually online, but the tradeoff is convenience. You can walk in with a bag of clothes and leave with money and less clutter.
Poshmark
Poshmark can be a good fit for nicer baby clothes, recognizable brands, and pieces that still look almost new. You take pictures, create a listing, set your price, and wait for someone to buy.
The platform also provides prepaid shipping labels for sales, which takes some of the hassle out of figuring out postage.

ThredUp
If your main goal is getting clothes out of the house without creating dozens of listings, thredUP can make the process easier. You request a clean-out bag, fill it with eligible clothing, and send it in.
thredUP handles the sorting, photography, listings, and sales for accepted items. The amount you receive per item may be lower than selling directly, but that can be a fair trade for anyone who has several bags of clothes sitting around.
Mercari
Mercari is another option for selling baby clothes, toys, shoes, and other items your child has outgrown. Listings are relatively quick to create, and you can sell individual pieces or bundles.
It can also be handy if your decluttering project goes beyond clothing. Instead of using one platform for clothes and another for toys or baby accessories, you can list several types of items in the same place.
Kidizen
Kidizen is focused on children’s clothing, shoes, toys, and gear, so the people browsing are already looking for kids’ items.
Boutique clothing, popular brands, and cute pieces in excellent condition can be a good fit. Having a more focused audience can also make it easier to find buyers who know what they’re looking for.
eBay
eBay is still worth considering if you have larger clothing lots, specialty items, collectible pieces, or brands that people specifically search for.
You can list items at a fixed price or use an auction format. Bundles organized by size, season, or type can also make sense if you have a lot of clothes to sell.

Craigslist
Craigslist can work well for local sales, particularly if you have a large amount of clothing or bulky baby gear. There’s no need to package everything up and pay for shipping.
A large bundle of clothes, a stroller, or several pieces of baby equipment can be easier to sell locally than online. Just use sensible precautions when arranging a meeting with a buyer.
The RealReal
If your storage bins contain designer baby clothes, it may be worth looking into The RealReal. High-end children’s brands such as Burberry, Gucci, Moncler, and Baby Dior can have resale value when they’re in good condition.
The platform handles much of the process, including authentication and selling, which can save you from creating individual listings for expensive pieces.
Consignment Shops
Local children’s consignment shops are another simple option. Many accept gently worn baby and children’s clothing, particularly current styles and seasonal pieces in good condition.
The amount you earn depends on the shop and its agreement with sellers, but you get the benefit of having someone else handle the sale. It’s also a nice way to support a small business in your community.
Garage Sales
Baby clothes tend to do well at garage sales because parents know how quickly children outgrow them. A rack or table filled with clothes organized by size can attract shoppers who are looking for affordable basics.
Selling outfits in bundles can save you from pricing every tiny shirt and pair of pants individually. You probably won’t make as much as you would selling premium brands online, but you can clear out a lot in one weekend.
If you’re planning to sell a large amount of baby clothing or gear, a simple garage sale bundle kit with labeled size bags, hangers, price stickers, and folding tables can make your setup easier to manage and simpler for shoppers to browse.
Instagram or Local Mom Groups
Local parenting groups can be surprisingly useful for selling baby clothes. Parents are often looking for affordable clothes in the next size, and buying from someone nearby can be easier than ordering a bundle online.
Instagram stories can work too, especially if you already have a local audience. Take clear photos, list the sizes and prices, and make pickup or shipping details clear from the beginning.
Don’t Forget Baby Gear
While you’re sorting through the clothes, take a look at the rest of your baby storage, too. Strollers, carriers, bassinets, bouncers, high chairs, swings, and monitors can take up plenty of room and may still have resale value.
Before listing any baby gear, check the current safety information and recall status. Some older products may no longer meet current safety standards, so not everything should be resold.
Selling outgrown baby clothes can take a little effort, but it can also turn an overflowing closet into useful cash. And once those clothes are gone, you’ll finally have room for the things your child actually wears now.
