How to Clean Your Kid’s Mattress (and Keep It That Way)

From late-night accidents to juice-box spills and mystery stains (seriously, what is that?), little ones and messes go hand in hand. As parents ourselves, we know that keeping your kid’s mattress can be quite the challenge, but it's an essential piece of keeping their sleep space healthy. 

Thankfully, if you’ve chosen a kids mattress with a machine washable, waterproof pad (like the Lullaby Earth Dream Easy Kids Mattress), cleanup is a whole lot easier. We'll walk you through the best way to clean your child’s mattress, what to do when accidents strike and how to keep their bed fresh and cozy for the long haul.

When it comes to your kid's first mattress, a waterproof pad can really save the day (or the night) by helping to protect the mattress from the kinds of messes parents know all too well. Whether your kid is potty training, navigating their first stomach bug or just really into juice boxes at bedtime, having a washable waterproof pad in place makes all the difference.

Why? Beyond convenience, it helps prevent deep contamination that can impact your child’s sleep and health. Liquids and accidents can seep into the mattress layers, leading to the growth of mold, mildew and bacteria. And once a mattress is compromised, it’s tough (if not impossible) to fully clean. A waterproof pad acts as a barrier, protecting the core of the mattress so it stays fresh and hygienic through all of childhood’s messiest milestones.

When accidents happen, here’s how to tackle them quickly and gently:

1. Blot, don’t scrub: Gently blot any spills or stains with a clean, absorbent cloth to soak up as much liquid as possible. Avoid scrubbing, which can push the mess deeper into the mattress.
2. Use a mild cleaning solution: Mix a small amount of gentle detergent or vinegar with water, then dab the area with a cloth or sponge. Let it sit for a few minutes before blotting dry.
3. Air dry completely: Allow the cleaned spot to air dry fully (ideally in a well-ventilated area or near a fan)to prevent lingering moisture that could lead to mold or odor.

1. Remove It Right Away: Strip off the waterproof pad and any bedding the moment you notice the mess.
2. Machine Wash: Toss the pad in the washing machine with gentle detergent. You can air dry or tumble dry on low, depending on care instructions.
3. Swap In a Spare: Having an extra waterproof pad on hand can save you from middle-of-the-night chaos.

While we can’t stop messes from happening (if only!), we can help you stay one step ahead and prevent any nightmare situations. Kids are bound to have a mess every now and then, so the best way to handle them is to be prepared for when they do happen. This way your kiddo – and you! – can get back to sleep and counting sheep.

Make sure to a waterproof pad every night, even during the day for naps or quiet time. Keep a backup pad and sheet set ready for quick changes, especially for those middle-of-the-night incidents. And when possible, encourage kiddos to keep food and drinks out of bed (we know, easier said than done).

Even without a spill or mess, kids mattresses can use a little refresh every now and then. No matter how clean your kiddo and their bedroom are, allergens like dust mites, plus sweat, body oils and other not-so-clean things build up over time. Doing regular cleaning maintenance on your kiddo’s mattress can help extend its lifespan, keeping it as supportive and comfy as can be. Here’s a safe, simple way to clean your kid’s mattress: 

• Sprinkle baking soda over the mattress.
• Let it sit for 20-30 minutes to absorb any odors.
• Vacuum thoroughly using a clean hose attachment. 
   

You can also open all the windows and let a little sunlight and fresh air help out! 

Kids spend a lot of their time in bed: asleep for bedtime, during naps and quiet time. Their little bodies are still growing and developing, so keeping their sleep environment clean can help support their well-being and give you peace of mind. From waterproof pads to quick spot cleaning, a little maintenance goes a long way in protecting their mattress and making sure their bed stays a safe, healthy place to rest, recharge and dream big.
