I was skeptical about the closures at first—thought they might not last. But three months in and they're still holding up great. Bought a new one because we loved it so much. The diaper change design is super convenient too. Big fan!
So stretchy and soft—he's obsessed. Love the embroidery too, it actually has meaning behind it. Only wish: make a neutral version so we can hand it down to baby #2. This quality deserves to be reused!
The fabric feels buttery soft, and the exquisite embroidery details are the perfect finishing touch that instantly elevates the overall quality. It’s both comfortable and adorable—I absolutely love it.
This fabric is incredibly soft—the kind of softness that makes you want to rub your face against it. It’s also very stretchy, and my baby loves wearing it.
Changing a diaper at 3 a.m. used to be a major ordeal—now, it’s all sorted with just a quick "rip and stick," and we’re both back to a sound sleep in under two minutes. It has completely transformed the experience.
The best quality and customer service!
Love it🥰💯🔥
Super cozy! Our son sleeps well in this and his Kaiya sleep sack.
Our kiddo loved fit perfect into this bodysuit. It was soft and breathable. My favorite part was the bottom to change diapers! The price is a little high but quality is 10/10
The material is super soft, fits true to size, and I love the fold-over cuffs. Definitely the best onesies we’ve used so far
Love the adjustable SnoozySeal closures, it makes diaper changes easier
The bamboo and Merino blend is so soft, love it
No smell and dry fast after sweatering. Great fabric.That is the best part I like.
I often bought sleep sacks in Kaiya baby so I would like to try this new series. As goood as their sleep sack.
We used this for camping and it was perfect for keeping our daughters temp regulated
The fabric is SUPER see through. The stitching is ridiculously rough, and the overall material is just not soft. I would not recommend at all. 2 stars because it’s cute you can personalize, but I don’t think we will ever use it.
Purchased for my new granddaughter, my daughter loves it for her.
The embroidery is so nice. Very cordial touch. The material is incredibly soft for my baby and I love the open and close feature for diaper changes.No snaps and no Velcro just a quiet magnet like feature.
Only pajamas our baby wears. Soft and good temperature regulation. Easy to get on and off.
Omg I really love the velcro thing 😍 so cool
GREAT quality! Soft, very well constructed- very happy!
Love how breathable yet warm the fabric feels??my baby never gets sweaty. The two-way zipper makes diaper changes super quick.
Love the soft material
It is exactly what we need now. We live in a an apartment where the temperature fluctuates in the night so we used it as pyjamas.
