How to Wash and Care for Your Zipadee-Zip and Flying Squirrel Pajamas

Your baby's sleep sack is a daily workhorse—it gets spit-up, drool, midnight diaper leaks, and the occasional mystery stain. Proper care not only keeps it looking and feeling great but also preserves the fabric's safety and fit. Whether you own a Classic Zipadee-Zip Swaddle Transition, a Fleece Zipadee-Zip, or a Flying Squirrel pajama, a few simple laundry habits will extend its life and keep your little one cozy.

Below are the best practices for washing and drying each type of fabric, plus stain removal tips that actually work. No special detergents or expensive treatments required—just a little know-how.

General Washing Rules for All Zipadee-Zip and Flying Squirrel Pajamas

Always close the zipper completely before tossing the sleep sack into the machine. This prevents the zipper pull from snagging other fabrics or the mesh lining inside. Turn the sack inside out to protect the outer print and reduce pilling. Wash in cold water on a gentle cycle—hot water can shrink the fabric and weaken elastic over time.

Use a mild, fragrance-free detergent. Avoid fabric softeners, bleach, or dryer sheets; they leave a residue that can reduce flame resistance and irritate sensitive skin. If you need to sanitize, add a half-cup of white vinegar to the rinse cycle instead of bleach. It's gentle and helps remove odors.

• Close zipper fully before washing to prevent snags.
• Turn inside out to protect the print and reduce pilling.
• Wash cold on gentle cycle with mild, fragrance-free detergent.

Caring for Fleece Zipadee-Zip and Flying Squirrel Pajamas

Fleece is warm and cozy, but it's also prone to pilling and static if not handled correctly. For fleece styles like the Sleeping Baby Pink Poppy Zipadee-Zip Swaddle Transition - Fleece or the Sleeping Baby Digging You Flying Squirrel Pajama - Fleece, wash on a gentle cycle with cold water. Avoid overloading the machine—fleece needs room to move so it doesn't rub against itself.

Tumble dry on low heat or air dry. High heat can melt the synthetic fibers, causing them to stiffen or lose loft. Remove the sleep sack from the dryer while it's still slightly damp to reduce static. If you see pills forming, use a fabric shaver (the kind used for sweaters) to gently remove them without damaging the fabric.

• Dry fleece on low heat or air dry to prevent melting and stiffness.
• Remove while slightly damp to reduce static cling.
• Use a fabric shaver to remove pills without harming the material.

Caring for Lightweight and Bamboo Zipadee-Zip Styles

Lightweight and bamboo fabrics, such as the EverSoft Bamboo Zipadee-Zip Swaddle Transition, are incredibly soft but also more delicate. Wash them in a mesh laundry bag to protect the fabric from snags and tears. Use cold water and a gentle cycle with a low spin speed. Never wring or twist the fabric when wet—it can stretch out the shape.

For drying, lay the sleep sack flat or hang it to dry. If you must use a dryer, choose the lowest heat setting and remove it while still slightly damp. Bamboo and lightweight fabrics dry quickly, so over-drying can make them stiff and brittle. Avoid direct sunlight when line drying, as UV rays can fade the print over time.

• Place bamboo and lightweight sacks in a mesh laundry bag for extra protection.
• Lay flat or hang to dry; use low heat if machine drying.
• Keep out of direct sunlight to prevent fading.

Stain Removal Tips for Baby Sleep Sacks

For fresh stains like breast milk, formula, or purees, rinse the spot with cold water immediately, then apply a small amount of mild detergent directly to the stain. Gently rub the fabric together (not against a hard surface) and let it sit for 10 minutes before washing as usual. For dried-on stains, soak the sleep sack in cold water with a scoop of oxygen-based stain remover for 30 minutes before washing.

Avoid using hot water on protein-based stains (milk, spit-up, egg) because heat can set the stain permanently. For stubborn stains on fleece, a paste of baking soda and water applied for 15 minutes before washing can work wonders. Always test any stain treatment on an inconspicuous area first, especially on printed fabrics.

• Rinse fresh stains with cold water immediately.
• Soak dried stains in cold water and oxygen-based stain remover for 30 minutes.
• Never use hot water on protein-based stains like milk or spit-up.

How Often Should You Wash Your Baby's Sleep Sack?

If your baby sleeps through the night without accidents, washing the sleep sack once a week is usually sufficient. However, if you notice drool, spit-up, or a wet diaper, wash it right away to prevent bacteria and odors. Having two or three sleep sacks in rotation—like a Classic Zipadee-Zip for warm nights and a Fleece Zipadee-Zip for cooler weather—makes it easy to always have a clean one on hand.

For the Flying Squirrel pajama, which has a more open design, you may get away with a little longer between washes, but check the armpit and neck areas for buildup. A quick spot-clean with a damp cloth can extend time between full washes. And remember: always follow the care label on your specific sleep sack, as fabric blends may have slightly different requirements.

• Wash weekly if no accidents; wash immediately after leaks or spit-up.
• Rotate between two or three sleep sacks to reduce wear and tear.
• Spot-clean Flying Squirrel pajamas between washes to extend freshness.

Caring for your Zipadee-Zip and Flying Squirrel pajamas doesn't have to be complicated. Stick with cold water, gentle cycles, and low heat drying, and your baby's sleep sacks will stay soft, safe, and ready for bedtime night after night. A little attention to fabric type and stain removal goes a long way in making these essentials last through multiple babies.
