The Organic Difference: Prioritizing Your Baby's Health and Our Planet

Comfort and Safety for Delicate Skin

Your baby's skin is up to five times thinner than yours, making what touches it all day truly matter. Our organic cotton onesies are free from harsh chemicals, pesticides, and synthetic treatments that can irritate sensitive skin or trigger reactions.

When we say “cloud-soft,” we mean it. Each onesie feels incredibly gentle against your little one's skin – the kind of softness you can see them relax into. Parents often tell us that their babies seem more comfortable and sleep better in our organic cotton, especially those with eczema or sensitive skin.

A Sustainable Choice for a Healthier Future

As a mom-founded company, I created Treehouse with a vision that extends beyond today. Our organic cotton uses:

• 91% less water than conventional cotton
• No toxic pesticides that harm soil and waterways
• 46% less carbon emissions during production

This isn't about perfect choices, but better ones. Each organic bodysuit represents our shared commitment to progress, not perfection.

Features That Matter to Parents

Ease of Dressing and Diaper Changes

We've been there, trying to dress a wiggling baby who suddenly has the strength of a tiny superhero! That's why our onesies feature:

• Thoughtfully designed lap shoulders that stretch gently over your baby's head without discomfort
• Nickel-free snaps at the crotch for quick diaper changes (and to prevent potential allergic reactions)
• Snaps that align easily, even during middle-of-the-night changes when you're half asleep

These aren't just “features”, they're solutions to the daily challenges we've experienced ourselves and heard from countless parents.

Ultimate Comfort and Protection

Beyond the organic materials, we've considered every detail that affects your baby's comfort:

• Ultra-soft ribbed organic cotton that moves with your baby, never restricting their exploration
• Smooth flat lock seams that won't irritate or leave marks on delicate skin
• Natural temperature regulation that helps prevent overheating while keeping them cozy

These thoughtful touches mean fewer disruptions to their day (and your night), creating more peaceful moments for everyone.

Finding the Perfect Fit & Style for Every Baby

Comprehensive Sizing for Growing Babies

Babies grow at their own unique pace, which is why we offer a full range of sizes from Newborn through 24 months. Our sizing is designed to accommodate cloth diapers comfortably while maintaining a snug, cozy fit for babies using disposables.

Based on parent feedback, we recommend sizing up if your little one is between sizes or at the upper end of a size range. This gives you more wear time as they grow (because they always seem to grow faster than we expect!).

Each size is carefully proportioned to maintain comfort and ease of movement, whether they're just beginning to roll or actively crawling and exploring.

Diverse Colors, Prints, and Gender-Neutral Options

Our collection features timeless colors and prints designed to mix, match, and be passed down:

• Versatile solids in earth-inspired tones
• Gentle prints that spark imagination without overwhelming
• Gender-neutral designs that work for any child and simplify hand-me-downs

We believe children's clothing should be free from unnecessary gender constraints, allowing kids to be kids while giving parents practical options that last through siblings and beyond.

Why Choose Our Organic Cotton Long-Sleeve Onesies?

Our Commitment to Quality, Durability, and Ethical Sourcing

Each onesie represents our unwavering standards:

• GOTS-certified organic cotton, ensuring the highest environmental and social standards throughout production
• Durable construction that maintains softness wash after wash
• Ethical manufacturing with fair wages and safe working conditions

Versatility and Value in Every Onesie

Our organic long-sleeve bodysuits are designed to be the hardest-working items in your baby's wardrobe:

Care Instructions: Machine wash cold with like colors. Tumble dry low or line dry to preserve softness and extend garment life. Organic cotton may shrink slightly with the first wash (we've accounted for this in our sizing).

At Treehouse Kids, we believe the smallest garments deserve the greatest care. Our organic cotton long-sleeve onesies represent our commitment to your child's comfort, your peace of mind, and our shared planet. Because when we know better, we can do better together.
