Nested Bean Zen Sack 2 Pack - Infant Sleep Sacks | Baby 6-15M | TOG 0.5 | 100% Cotton | Eases Transition After Swaddle | Aids Self-Regulation | 2-Way Zipper | Machine Washable

These work very well. Weight can be used on stomach or back depending on how child sleeps. They are also very well made.

A coworker gave me a look like I was an irresponsible parent by buying this for my baby. She wasn't specific but implied the weighted egg is somehow dangerous for sleeping...maybe SIDS or some nonsense?! Anyway, trust me, the egg does not weigh more than a few ounces and it's absolutely safe. This same coworker is a neurotic basket case and she still breast feeds her 4 year old soooooo....yeah. My son transitioned to this sleep sack from a full swaddle with no issues. He sleeps very well in it. I suggest buying two because you WILL end up with a leaky diaper in the middle of the night at some point and you'll be glad you have an extra one!

These have been our go to sleep sack since the beginning. Our baby loves them and has slept great with them. It’s a great quality material, the zipper and snaps are durable. I feel very safe using Nested Bean products. I will forever love Nested Bean. I just wish they made warmer sleep sacks with sleeves for winter.

Good product. I wish it has more evenly distributed weight to it. Great leg room and very soft.

My baby was very comfortable in his Nested bean sack. It really help him feel secure to fall asleep in his own bed.

My baby has been sleeping so great with this! It was our transition from the lovesac when he started rolling.

Mi bebe siempre se despierta las primeras veces que intento ponerla en la cuna, hay días que he tenido que ponerla mas de 6 veces y siempre se despierta, con este traje muchas veces se queda de la primera vez que la pongo. He intentado que duerma sin el traje y al final siempre tengo que ponérselo. Lo recomiendo totalmente.

We LOVE this brand and have several of their products. Our daughter has been sleeping through the night since about 3.5 months.. I think Mostly because of the nested bean products! Would highly recommend them!
