Why do we love what we do?
We help all parents raise happy and healthy children while also getting the rest they need.
What problem are we solving?
Modern parents often have little experience and little hands-on help from friends and family.

The softest Snoo sack yet and the Tie Dye is adorable!
We own a few different Snoo sacks, but this Tie Dye Rainbow version is by far my favorite. The 100% organic cotton feels noticeably softer and higher quality than the standard white ones.Why we love it:• Design: The tie-dye print is super cute in person vibrant but still gentle enough for a nursery.• Softness: It washed really well and stayed incredibly soft against my baby’s skin.• Function: It works exactly like the original sacks (clips in easily), but adds a nice pop of color to the bassinet.Verdict:If you want to mix up the plain white look, this is a winner. Highly recommend for the softness alone!

must buy
The Happiest Baby SNOO Sleep Sack is excellent quality. The 100% organic cotton is soft, breathable, and gentle on baby’s skin. The design makes swaddling easy and secure, helping baby feel calm and comfortable. It’s well made, washes well, and holds up beautifully over time. A great investment for better sleep and peace of mind.

Perfect swaddle
Can’t live without!! The ONLY swaddle our baby can’t escape! Extremely easy to use. Color exactly as pictured. Has lasted for several months, does start to lose velcro stick after about a month or 2 but the zipper keeps it secured. Not super warm, perfect for 70° sleeping temps!

Cute Print that washes well
The print on this is so cute! It did start to fade after several washes, but the design actually looks cute faded, almost like it was always that way. We love the overall quality of the Happiest Baby brand and have never had issues with the Velcro or clips

5 week old baby sleeps happily in his Snoo sacks!
I purchased the Snoo Sleep Sack in the Teal Planets color in size small and I have been very happy with it for my 5 week old. The fabric on this version feels noticeably softer and stretchier than the plain white Snoo sacks that I also own. My baby is over 9 pounds and 22 inches long and the Small is still fitting him well while allowing him to sleep comfortably. It’s so easy to swaddle him with the velcro and zip up closure.It does a great job regulating temperature. Even during winter we do not need to layer him heavily and he sleeps very well in this sleep sack. He always seems comfortable wearing it and despite being only 5 weeks he is starting to have long sleep stretches! I definitely think part of this is because of how cozy he feels in his Snoo sacks! I would definitely purchase more of these and would choose this fabric over the plain white versions due to how soft and flexible it feels.

Finally, the Swaddle That Makes Bedtime Easy
Hello all, We absolutely love the Happiest Baby SNOO Sleep Sack! My wife has tried multiple other brands before, but this one truly made her day. The 100% organic cotton feels so soft and gentle on our baby’s skin, and we love that it’s doctor-designed to promote healthy hip development. The ivory lemons design is adorable, and the X-Large size gives our little one plenty of room to grow comfortably. It’s made bedtime so much easier and more peaceful for both baby and parents. Highly recommend to any new parent looking for a safe and cozy swaddle!

Switched to medium
I switched to medium once my baby weighed 11 pounds. Before than I was using the small. I usually order two of each just in case there is an accidental blow out or to switch the colors every now and then. I love how this is an easy way to swaddle my little one and like the fit between the small and medium since I have experienced both. It’s a good value for the money as they do last a long time. It’s also very easy to slip on and off of the snoo.

Great product, bad smell
Works fine. Fits the snoo, but had a bad “packaging” smell when it arrived. Had to wash it twice.

I’ve been using the snoo for about 4 months now. We had received some old swaddles where there wasn’t enough room around the hips to allow for my babies legs to be in frog position while he slept, so i decided to purchase the newer version and they’re amazing. There is so much room for him to be comfortable. The velcro is sturdy and snug. The sizing is accurate. The buttons around the shoulders allow you to use it as a sleep sack once your baby isn’t being swaddled anymore.Cleaning is a breeze, very easy to get stains out of it even though it’s light in color.The only disappointing thing was that the color was more beige/yellowish than white.We also had to wash it a couple of time once we received it as it was hard to get that factory smell out of it.

A great sleep suit. Secure and cool for the summer months.

C’est parfait pour la naissance, mon fils arrêtait pas de sursauter et de taper les parroi du berceau avec ses petits doigts. Avec cette gigoteuse il est bien serré, il dort beaucoup mieux.Je recommande mais attention c’est vraiment petit, ne pas s’attendre à l’utiliser trop longtemps.

!La verdad me gusto mucho este producto! Va creciendo junto a tu bebé, aunque considero que debería de haber tamaños más grandes, mi bebé solo lo pudo usar 1 mes (de 4-5 meses), compre el grande, y aunque no pesa ni los 8 kilos de lo largo le dejo de quedar.
