Safety Tips for Secondhand Baby Gear

Becoming a parent comes with endless decisions and an ever-growing list of baby gear. From strollers and high chairs to bassinets and baby carriers, the costs can add up fast. That’s why many families turn to secondhand baby gear as a way to save money, reduce waste and keep those barely-used items in circulation.

But while hand-me-downs and thrift-store finds can be a great way to stretch your budget (and your eco-conscience), not everything is safe to reuse. Safety standards evolve constantly, and some products simply aren’t designed to be passed down. Before accepting or buying used baby items, here’s what every parent should know.

Babies outgrow their gear faster than you can say “newborn stage.” Swings, sleepers and bassinets often see only a few months of use, making them prime candidates for secondhand shopping. And with more families embracing sustainability, it’s become common to swap gear within friend groups, neighborhood buy-nothing pages or community resale events.

Opting for secondhand baby items can be a smart, sustainable choice. It reduces waste, keeps usable products out of landfills and helps parents spend more intentionally. Still, it’s essential to balance those benefits with an awareness of baby gear safety.

Just because something looks new doesn’t mean it meets current safety standards. In recent years, the Consumer Product Safety Commission (CPSC) has introduced updated rules around everything from infant sleep products to crib slat spacing. Some items that were considered safe even five years ago might not be today.

Used gear can also have hidden wear – a cracked frame, frayed strap, missing screw – that compromises its structure. And while sentimental hand-me-downs are part of many family traditions, parents should always prioritize their baby’s safety over nostalgia or savings.

When it comes to certain products, “new” is a must.

A firm, supportive crib mattress is one of the most important parts of your baby’s sleep setup. Used crib mattresses may harbor bacteria, mold or allergens from years of use. They can also lose their shape and firmness over time, increasing the risk of unsafe sleep environments. If you’re looking for a safer, breathable option, Lullaby Earth crib mattresses are made with healthier materials, waterproof surfaces and firm support that meets the latest CPSC and pediatric recommendations.

Car seats have expiration dates (usually six to ten years from manufacture), and safety standards change regularly. A used car seat may have been in an accident – even one you can’t see evidence of – which compromises its ability to protect your child. Always buy a new car seat and register it so you’ll be notified of recalls.

Pacifiers, bottle nipples and teething toys may look fine at first glance, but they’re meant to be replaced regularly. Over time, materials like silicone and rubber can break down with repeated exposure to heat, moisture and cleaning products. This wear creates tiny cracks and crevices where bacteria can grow, even if the surface looks spotless. 

When it comes to breast pumps, safety and hygiene go hand in hand. Unless the pump is specifically labeled as a closed-system model, meaning there’s a physical barrier between the milk collection kit and the motor, it’s best not to buy or borrow one secondhand. In open-system pumps, milk and moisture can enter the tubing or motor housing, where bacteria and mold can grow unseen. Even if parts look clean, it’s nearly impossible to sanitize internal components completely.

Other baby items can be safely reused if you take the time to inspect, clean and verify them properly.

Secondhand baby clothes are a great find. Just make sure to check for loose buttons, long drawstrings or frayed edges that could pose choking or strangulation hazards, and prioritize organic and non-toxic materials that aren't treated with flame retardants. Wash everything in fragrance-free detergent before use.

Avoid any toys with chipped or peeling paint – especially vintage pieces, which may contain lead-based paint that wasn’t regulated until the late 1970s. Check for loose parts, sharp edges or small detachable pieces that could pose a choking hazard. For plastic toys, look for cracks or discoloration that may indicate brittleness. Whenever possible, verify that the toy meets current ASTM safety standards and give everything a thorough wash or wipe-down with a baby-safe cleaner before use.

Larger gear like high chairs and strollers can be a great secondhand find, but only if every part is working exactly as it should. Inspect the entire frame for cracks or bending, and test all moving parts: harnesses, locks, brakes, recline levers and folding mechanisms. Fabric covers should be washable and free from tears or sagging areas that could trap your child. Make sure the harness straps are strong, adjustable and secure firmly in place. And, if anything feels loose, squeaky or sticky, it’s safest to skip it.

Dressers, changing tables and bookshelves often last through multiple children, but time and wear can affect their safety. Check that each piece is stable and level, with no missing hardware, peeling finishes or splintered wood. For taller furniture, always use anti-tip wall anchors (many are available for free through the CPSC’s Anchor It! program) to prevent tip-over injuries. 

Before buying or accepting any used baby gear, take a few minutes to check for recalls. It’s simple and could prevent a serious safety risk.

Start with the CPSC recall database, which lists current and past safety alerts for children’s products. You can also check the manufacturer’s website for model-specific recalls. Look for a sticker or label on the item itself – this usually lists the model number and manufacture date.

If you can’t find identifying information or the label has worn off, it’s best to skip that product. In baby gear, missing information is a red flag, not a coincidence.

Even when gear passes the safety test, it still needs a thorough clean before it’s nursery-ready.

Here are a few tups for cleaning secondhand baby gear:

• Wash fabric items (clothes, bedding, soft toys) in hot water using a baby-safe, fragrance-free detergent.
• Wipe down plastic and metal parts with a mild soap and water solution, followed by a disinfecting wipe or baby-safe cleaner.
• Sanitize large items like strollers and high chairs by wiping every surface, especially harnesses, trays and handles.
• Let everything dry completely to prevent mildew or bacterial growth.

When in doubt, remember: clean means more than what you can see.

Buying secondhand is an excellent way to practice sustainability, but the goal is to do so responsibly. Whenever possible, choose quality over quantity and focus on products designed to last. Lullaby Earth crib mattresses, for instance, are made without scary chemicals like flame retardants, phthalates or polyurethane foam, so they’re not only safer for your baby, but also for future generations.

If you decide to pass gear along to another family, include the model number, date of manufacture and any original instructions. Clear information helps ensure the next parent can use the product safely, too.

There’s something special about using secondhand baby gear, whether it’s a stroller your cousin once used or a quilt your mom sewed years ago. These items carry stories, memories and a shared sense of community. But as every parent knows, safety always comes first. With a little research and care, you can make secondhand gear part of your sustainable parenting journey without compromising peace of mind. Because when it comes to your baby’s comfort and safety, the best choices are the ones made with love and intention.
