Review on 👶 Nested Bean Zen Sack: Gently Weighted Sleep Sacks for Babies 0-24 Months - 100% Cotton, Perfect for Newborn/Infant Swaddle Transition, 2-Way Zipper, Machine Washable by Natalie Gregory

When fully unfolded it's literally just a sleeping bag with little weight in the chest area. You can probably recreate this with a regular sleeping bag and a small bag of rice or dried beans. That's what we felt when we opened it. But we had no doubts. At first we thought it worked fine but then our 4 month old started tossing and turning like crazy at night. Finally it turned out that it was the sleeping bag. So we decided to try the regular light sleep our friend gave us, which was actually meant for a 12 month old baby. It's pretty big for him, but it worked just as well, if not better than this one.
