Nested Bean Zen Sack® Winter | Infant Sleep Sacks | Baby 6-15 M | TOG 2.5 | 100% Cotton | Eases Swaddle Transition | Aids Self-Regulation | 2-Way Zipper | Machine Washable

We were struggling trying to find ways to put our babygirl down throughout the day without her throwing a fit. This sleep sack is literally the only thing that worked. She has been doing so good going down. We still sleep together at night but throughout the day when I want to get stuff done I just use this.

I’ve tried the usual sleep sacks, and they keep my 3 mo. old warm, but they don’t keep her asleep and wakes up easily. I was hesitant to buy this because of the price but I decided to try it. It works just as advertised! Now, whenever we put her down, she stays asleep for 3 to 4 hours at a time.The only reason why I’m giving at four stars is because they need to re-consider their sizing. My baby is almost 4 months old and the 0-6 monthssleep sack is small on her. It seems like the sleep sack would fit more 0 to 3 months.

These are the best sleep sacks especially if you live somewhere colder.

This works great as a regular sleep sack. The weighed part has not made a difference for us.

I love the Nested Bean sleep sacks. I had a lightweight one that was given to me as a gift for my baby shower and my baby started using it around 4 months and slept all through the night. We compared this sleep sack to the Dreamland Baby sleep sack and you can't compare. The only thing that I am bummed out about is that my baby likes to sleep on her back and on her stomach so I feel like I can't use the sleep sack anymore because the weighted part might be uncomfortable on her back or chest. The only other thing I can recommend is to size up. I got the 6-12 month sleep sack and my l/o is about to be 7 months and is already outgrowing it.

We switched over from the Burt’s bees quilted sleep sack after our 6.5 month old started waking up almost every hour looking for her pacifier.The first night we put this on her she only woke once. Last night she slept from 8:30 pm to 8:30 am. I also put an extra pacifier in her crib for her and that seems to also help.This sack is super soft, long so there’s room to grow, and much warmer than the Burt’s bees. The beans are not too heavy either! We also have the dreamland but it’s so heavy I’m afraid to put it on her.Worth the purchase!!!

I debated spending the money when there are less expensive sleep sacks on the market. All the reviews are raving so I took a shot for my baby who was transitioning from the swaddle. Simply put, just buy it. Do it. I now have a warm weather and a winter weather option and they have changed the game. Now, I’m sure this sleep sack is only part of the equation, but my 5 month old has been sleeping through the night consistently for 7 weeks and I feel like a real human again.

This sleep sack is magical. We had been struggling with our baby boy's sleep since 4 months on the dot. He was previously a great sleeper, sleeping 7-8 hours at a time since about 5 weeks. 4 month sleep regression hit hard, with him waking up every 1-2 hours like clockwork. We dealt with this for a month a half hoping that he would figure it out and get back to sleep, but he always needed his pacifier. We had moved him to his own bed hoping that it might help if we just didn't hear his every little noise (slamming his legs down like a whale, little whines, etc.). Nope! Way worse! Now he woke up screaming at the top of his lungs.In comes Nested Bean, looking for anything to help I saw an ad for this sleep sack and thought 'Well, it can't hurt'. We gave it a try, and I'm not kidding the very first night he fell asleep in his crib almost instantly after putting him down. We were incredibly optimistic after this happened. That night he did wake up 2-3 times, which was still an improvement over the previous month. The night after that, he woke up maybe 2 times. And by the third night, just as they say, 'better sleep in 1-3 nights', he was waking up once at 9:30pm for a feeding and then out until 6:30am. This has continued for a week.We're remaining cautiously optimistic and know that this could change at any time. At the very best, this sleep sack has helped him to learn how to self soothe in his crib on his own. At the very least, it has given us a much needed week of sleep. Worth every penny. I know this won't work for everyone, but it genuinely worked a miracle for us.

Very warm and Cosy baby .An excellent safe sleep option that you know baby isn’t going to be cold in .

My baby knows it’s time to sleep when I zip him in. We bathe him, dress him, and zip him into the sleep sack with a warm bottle. It’s been like clockwork since we introduced this to our night time routine! This sleep sack keeps him warm and snuggly, and the weighted centre really makes a difference in how fast he falls asleep. Obviously this doesn’t make up for teething or cluster feeding, but it has improved our night time routine in a big way. We also love the warmth rating (2.5 tog) great for Canadian winters. We wash it using the cold/gentle setting and air dry/ use a no-heat dryer setting. There has been zero wear and tear and no shrinkage in the 2 months of daily use and many washes.

My baby is 4 months old and average height for his age. We have the lightweight sack for the summer, love it, so we purchased this warmer model in the 0-6 month size since the other one we have still leaves room for our baby's growth.Unfortunately, when we washed it, this model shrunk SO much! We had to return it because it wouldn't even fit him now, so much less this upcoming winter.We did however order a size up since the overall quality of the sleep sack is great and the shoulder snaps really sets it apart from all other brands we've tried. It's just so easy to put on, even when your baby is sleeping. It's expensive but worth the expense IMO.

Our baby is 9 months and we ordered the large or 15-24 months. He has lots of room to grow in it. Not as fluffy as some other brands we tried so hoping it is warm come the cold days. Baby seems to love it for these early winter days. I did read the print about the bean bag stuff being spread out through the chest area so at first, I thought the bean had exploded haha.

This sleep sack has been a game changer in terms of how well my baby sleeps and peace of mind that she won’t roll off the bed or jump off her crib. However, as other buyers have mentioned, they run small around the 12 month mark. It truly doesn’t go until the 15 month mark and for that reason, I am taking off 2 stars.
