Great sleeper sacks
These are not only adorable patterns but lightweight and breathable which is perfect for the warmer summer nights. They fit my little man perfectly, and he seems to like them and sleeps very comfortably in them. I absolutely love the double zipper so if I need to change him at night I don’t have to completely unzip him. Another feature I love as well is that it zips from bottom to top so I don’t ever have to try to get the zipper started and have to try getting it to hook with my squirmy little guy who’s always trying to get away and be on the move (moms I’m sure you know what I mean). I would definitely recommend and purchase again

Perfect Sleep Sacks!
Perfect sleep sacks for my baby, bought for him at 6 months and they are perfect to grow with him! Heâs now 9 months and they are still a great fit! Very durable and good material! Love the fabric and colors!

Soft, comfy and tough
Love these! They look nice, are lasting a long time as my son grows, and they fit great. They are long enough that my son has been using them for atleast 6 months and i haven’t had to buy any new ones!

Good quality
These are fantastic. We rotated them for 6 months. Never an issue quality. Washed well and easy to use.

Lightweight sleep sack
This lasted for my son for almost a year. I bought these when they were too big but he loved them.

Runs small
These are great, HOWEVER — my baby is pretty small for her age. We got the 12-18 month onesies when she was about 9 months old, and even though she’s in like the 9th percentile, already at 13 months she barely fits in these. I would definitely recommend ordering a larger size than you think you need! Also bc you can always put a small baby in a bigger sleep sack.The fabric quality is great, ask natural fiber so it jeeps my baby cozy while still being breathable. She sleeps great in these. I just know there’s no way they’ll fit until she’s 18 months, which is a real shame! I was hoping to not have to but any more sleep sacks after this batch…
