This is the kind of baby outfit you keep reaching for every laundry day 🤍 Super soft—like cloud soft—and gentle on my baby’s skin (no irritation at all 🙌). I love how breathable it is, especially for active babies or warmer days. Plus, it still looks cute and cozy at the same time. Definitely one of those ‘worth it’ pieces for comfort + style ✨

Renee

I was looking for a well made organic cute bunny baby fit for my little girl’s one year birthday. This product was not only beautiful and soft, but it also has UPF 65! This was great because her party was held outside in the hot sun. I also love the seamless embroidered design and that the material is soft and healthy for my baby girl’s skin! I highly recommend this product and my daughter will be wearing more beautiful outfits from them.

Angela

As a nicu mom, I’m really picky about what touches my baby’s skin, and this onesie completely won me over. It’s unbelievably soft like the kind of softness you notice immediately. It’s like the perfect hug that can keep your baby feeling safe. My baby stayed comfy all day, and I honestly loved cuddle time even more because of it. She usually sweats easily and not of fan of long sleeves but she didn’t even complain about this one!! @kottonspa!! You won her heart❤️

Now I finally understand the hype around Supima cotton 😍 KottonSpa pieces feel unbelievably soft, breathable, and luxurious on the skin. The quality honestly stands out the moment you wear it. Cute, comfy, and premium all at once ✨

Super soft and breathable fabric — perfect for my baby’s sensitive skin 🤍 You can really feel the quality of the 100% Supima cotton. Great for hot Texas weather!

Emily Munday

These are incredible. I don’t think I’ve ever encountered softer pajamas! Kotton Spa sent us some for us to try, and I can say we’re obsessed with the softness. No cotton I’ve encountered has ever been this soft and my 3 year old loves them.

Catherineann

This romper is made with such attention to detail! The softness of the supima cotton is incredible- truly the softest cotton I’ve ever felt! The embroidery is so darling as well, and it’s great that it isn’t against my baby’s skin on the inside. My baby seemed very comfortable in it, and got so many compliments!

Momma

Such a comfy soft brightly colored suit for my almost 2 year old. He was absolutely adorable in it!

Angela

Originally made as washcloths, but my baby girl ended up using them as her cuddle lovey instead. They’re incredibly soft, gentle on her skin, and clearly comforting enough that she wants them close all the time.

As a NICU mom, comfort and quality matter so much to me, and this Supima cotton blanket did not disappoint. It’s incredibly soft, breathable, and feels gentle and comforting. A beautiful quality blanket that brings a little extra comfort during a delicate time.

Chithra Kannan

Absolutely love this outfit! The fabric is so soft and gentle on my niece’s skin. She looked comfortable, happy, and could move around easily all day. Great quality, beautiful design, and perfect for little kids. Highly recommend!

Victoria Serra

I received the kimono, booties and the swaddle as a baby shower gift and I love them so much! The packaging itself is so beautiful, perfect for a gift, and the quality is great and so soft. I can’t wait to use them when my baby is born.

Katelyn

I love how darling this bib is, it's so simple but has such a beautiful aesthetic to it. It's super soft and looks cute with so many outfits!
