Physiotherapy standards were used to determine the appropriate weight in the Zen Sleepwear. Nested Bean addresses this concern on its website: "The weight is light and flexible, so it will nearly flatten underneath your baby's body.

So the thought of putting Ellie to bed with a weight on her really scared me at first - what if it weighed her down and she wasn't strong enough to roll over? I do my best to follow the American Academy of Pediatrics safe sleep guidelines, which rule out many comfort items in the bassinet or crib for infants such as blankets, pillows, and stuffed animals. For the 15 to 24 month size, the weight is evenly distributed across the chest (or back, depending on how you use it). Ellie is a tummy sleeper and was starting to roll on her own, so we actually put the Zen Sack backward so that the weight is on her back when she sleeps - which the brand says is fine to do for babies who are starting roll. There is also a two-way zipper that starts under one armpit and follows the outside seam around to the opposite bottom corner it's a nice feature for middle-of-the-night diaper changes.įor the smaller sizes (12 months and under), the weight is concentrated in an oval on the baby's chest. The top snaps at the shoulders with a looser and tighter option. The material is really soft, and it's simple to get the sack on and off. We keep the room around 70 degrees, so Ellie always seems to be comfortable at night.

We layer it over a long-sleeve footed pajama. The Premier is also made with a blend of bamboo and cotton, while the Classic and Winter are both 100% cotton. The higher the TOG, the warmer the sleep sack. The brand also offers swaddles, bodysuits, and footie pajamas with the same weighted feature.įor the Zen Sack, there is a Classic, Premier, and Winter version, each with a different TOG, or thermal insulation. The Zen Sack is a sleep sack, or wearable blanket, that comes in many sizes - 3 to 6 months, 6 to 12 months, and 15 to 24 months.
