The Ollie World is a small biz based in Rancho Cucamonga, California, founded by a foster mom who wanted to make her own swaddle that could meet all of her foster son's needs.

Promising review: "I took an online sleep-training for babies class and the instructor highly recommended this product in her class. I came to Amazon to buy it immediately but the price tag stopped me. I refused to buy it, moved on, and looked for other options. I ended up buying three other swaddles that were cheaper but did not work (my baby got his hands out of ALL of them and woke himself up in the middle of the night every time). So after four weeks of buying swaddles, trying them out, then returning them because they didn't work out, I finally gave in and bought the Ollie Swaddle hoping it would be worth it. And YESSSS, it works!!! It is the ONLY Swaddle my baby cannot get his arms out of!! I found out about it when my baby was 6-weeks-old and didn't buy it till he was 10-weeks-old because I was afraid of spending that much but omg, I wish I had bought it sooner. This is the HOLY GRAIL of swaddles!! I love love love it. So easy to use and so soft but strong at the same time. This is GENIUS!! Buy it now please!! It will help your baby sleep SO MUCH BETTER :)" —AnileyR
