New Happiest Baby Sleepea Sack Swaddle Wrap (Ivory Planets - Medium)
The Happiest Baby Sleepea Sack Swaddle Wrap is a doctor-designed infant swaddle that securely wraps babies for safer sleep. Made from GOTS-certified 100% organic cotton, it features secure inner flaps, a two-way zipper for easy diaper changes, and breathable mesh panels for temperature regulation. Based on parent feedback, this swaddle runs small, so sizing up is recommended, and it is also suitable for arms-out transition when babies begin to roll.

Easy process
Super easy to order. Arrived on time and in great shape!
Kidsy Customer Service Review
Kidsy had a great selection of deeply discounted baby gates. Unfortunately, there was a piece missing when I received my package. I didn't realize it until after the 14 day return/exchange window. But I reached out, and they were willing to send me the piece anyway at no extra charge. I really appreciated the customer service.

My item shipped very quickly and I received it about 3 days after I ordered it! It came in an extra protected box as well! Very pleased with my purchase!
So grateful
Found what I needed at a price I could afford.
Good stuff

I appreciated the detailed description
I appreciated the detailed description, I knew I was getting a floor model and it came in perfect shape at a much reduced cost. When I thought the cupholders weren't included, I reached out to them and then we found them and they were very responsive and thankful that I let them know. Everything is fine.
Everything was great
Fast shipping, clear product info, no surprises.

Very happy
Really happy with my order. Shipped fast and clean.
Great, trustworthy experience
Great deals, easy checkout with lots of payment options, shipped very quickly, and everything was packed well and looked exactly as it was described! I didn't end up needing any intervention with my shipping experience but appreciate the option to cover lost packages for a minimal fee, especially as we get into the late and lost package holiday season. I'll definitely be getting more of my baby gear from Kidsy.
Better than marketplace
Safer and easier than buying used on Facebook.
Better than expected
Everything came packaged well, looked brand new. Super impressed.
Quick response
Ordered a gate prior to this one, UPS lost it on route. I reached out to Kidsy via email and they secured a refund from UPS. Was hesitant to order again, but I couldn't find the gate at a more reasonable price. 2nd order arrived with no issues. Gate is sturdy and the dog (Husky) hasn't gotten through it (he's an escape artist). Quick delivery from start to finish.
Fast delivery
Order arrived in 2 days and looked perfect.

Compatibility of Happiest Baby swaddles with non-Snoo bassinets
User asks if Happiest Baby swaddles work without Snoo; commenter confirms: 'Yes! I use them with my regular bassinet. They are the best swaddles I've found - my baby can't break out and sleeps so well.' Another user adds: 'They fit snugly and the material is breathable.'

When to stop using Sleepea swaddle
User asks when to stop using Sleepea; replies: 'Once they start rolling, you need arms out. Sleepea has the arm holes, but I found it still restricted her legs and chest. We switched to a Halo sleep sack.' Another: 'I used arms-out Sleepea until he outgrew it, but he rolled fine.'

Sleepea sizing advice
Thread discusses sizing: 'I found they run small. My baby is 12 lbs and the medium is already snug. Size up if you're unsure.' Another comment: 'The leg area is narrow, so if your baby has chunky thighs, it might be too tight.'

Comparison of multiple swaddle brands
User compares swaddles: 'I've tried Halo, Love to Dream, and Sleepea. Sleepea is the only one that kept her arms down all night. But getting her arms in is a struggle—definitely not 5 seconds.' Another: 'Love to Dream was easier, but she escaped.'

Frustration with swaddle purchases, including Sleepea
User vents: 'I've spent so much on swaddles. Sleepea was supposed to be the one, but it's so hard to get his arms in the band. I'm returning it.' Counterpoint: 'I love Sleepea! It's the only one my baby can't Houdini out of. The 5-second thing is marketing, but it's worth the extra minute.'
