I donât know how I lived without this
My baby knows itâs time to sleep when I zip him in. We bathe him, dress him, and zip him into the sleep sack with a warm bottle. Itâs 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 doesnât 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.
Not sure if the weight makes a difference, but a good sleep sac regardless.
We have a baby who struggles to sleep, so we’re always looking for help. This is our second size of these weighted sleep sacs. I’m honestly not sure if the weight helps or not, but the bag is warm and soft, and we like the snap shoulders and two way zip. So even if it doesn’t help, I would still buy this product.
Warm and slightly weighted
Bought this when we were going through the 4month sleep regression. Within 4 days she was back to only getting up once a night. I don’t know if it was the product or just timing! Overall it’s a great, warm sleep sack. Washes and dries well! Will be purchasing when she outgrows this size. (2.5 tog).
Practical, but not worth the price
I am a newly first time mom of twins and was looking for ways of making them sleep in their bassinets all night. After 3 nights, I realized that weight component was not necessarily what I was expecting. They still wake up multiple times to ask to be taken. Another down side for me is the fact that is too long and my babies are premies so they do not even use half of the space. I give it 3 starts since itâs very easy to open and close specially for the 3 amFeeds. Do not recommend for premies or very small babies
Love love love
Love these and so do my babiesI got these for my twin boys at the time they were 31/2 months old and for the past month they have slept through the NIGHT! My boys just love them, they get there last bottle, then a bum change we pit them in there zen bags have a cuttle and they are out cold. Will be getting again for the next age size.
Best purchase ever!
This is by far the best product we could have bought. The quality is amazing, and it exceeded our expectations. Our baby slept an hour longer than usual thanks to this sleep sack â itâs such a game-changer! Everything about it is fantastic, and I highly recommend it to everyone. Itâs worth every penny, every dollar spent!
Order a size up. It shrinks A LOT in the wash
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.
Love it
Been using this brand since babyâs born and baby likes it itâs soft and comfy
