You bring home your precious baby and carefully choose products that will keep them safe and cozy. Sleep guidelines were always so important to me. It’s so important that we keep our babies safe overnight while they sleep. As a mom of 3, you can imagine that I’ve tried a few, and I want to share the one that I recommend to everyone. Additionally, I’ll dive into the importance of TOG ratings, the safety of using sleep sacks over loose blankets, and the American Academy of Pediatrics’ recommendations for a safer sleep environment. I’m going to share the sleep sacks I’ve used and the one that I’ve found to be the best baby sleep sack. 


The Best Baby Sleep Sack – Our Favorite Wearable Blankets


New parents often worry a lot about baby’s sleep. We worry about choosing the right monitor, transitioning from a swaddle, and if we’ll ever sleep again. I tried a handful of wearable blankets with my first, and by the time I had my third, knew exactly what blanket he’d wear. In this guide, I’m going to discuss the Mori Sleep Sack, Kyte Baby, Woolino, and the Merlin Suit, and why the Mori Sleep Sack is my personal favorite. I should mention that I never tried the Nested Bean and am very much against any sort of weighted sleep sack for safety reasons. 


The Importance of Safe Sleep

For safety reasons, babies should never have anything in their crib that could pose a risk of suffocation or strangulation. This includes loose blankets, pillows, and even stuffed animals. A  baby sleep sack, also known as a wearable blanket, is a safe alternative to a loose blanket. The American Academy of Pediatrics (AAP) recommends using sleep sacks to reduce the risk of Sudden Infant Death Syndrome (SIDS) and ensure a safer sleep environment for your baby. Sleep sacks provide warmth and comfort without the hazards associated with loose blankets, making them an essential item for any nursery.

Once your baby turns one, it is safe to allow them to have a small lovey. I would recommend choosing one without any pieces that can come detached, like buttons. Each of my babies received a Slumberkins snuggler for their first birthday, and slept with them for years. 

At two, it is safe for your baby to sleep with a toddler-approved pillow and blanket. 

The AAP recommends placing your baby on their back to sleep, using a firm mattress, and keeping the crib free of loose blankets, pillows, and stuffed animals. A sleep sack provides the warmth and comfort your baby needs without the risks associated with loose blankets. By adhering to these guidelines and selecting a high-quality sleep sack, you can help ensure your baby’s safety and promote restful sleep.



A TOG Guide

TOG, or Thermal Overall Grade, is a unit of measurement used to indicate the thermal insulation of a product. In the context of baby sleep sacks, the TOG rating helps parents choose the right sleep sack for the room temperature, ensuring their baby is neither too hot nor too cold. A lower TOG rating (0.5-1.0) is suitable for warmer months and room temperatures above 75°F, while a higher TOG rating (2.5-3.5) is ideal for cooler temperatures below 68°F. I usually keep my children’s rooms around 68-70° since I remember reading those temperatures are optimal, and choose a 0.5 or 1.0 TOG wearable blanket. Selecting the appropriate TOG rating is important for maintaining a comfortable and safe sleeping environment for your baby.


Transitioning from a Swaddle to a Wearable Blanket

I used the Merlin Magic Sleep Suit to help my babies transition from swaddling to a wearable blanket. The Merlin is made from a soft, breathable jersey fabric and provides a cozy, secure feeling. Baby’s arms can move in the Merlin, but it reduces the startle reflex, allowing for more restful sleep. The Merlin Magic Sleep Suit should be worn while your baby comfortably sleeps on their back. I did always make sure the room was closer to 68° and that feet were covered when my babies wore this.  


The Mori Sleep Sack

My personal favorite is the Mori Sleep Sack. Made from a blend of organic cotton and bamboo, this sleep sack is incredibly soft and gentle on a baby’s delicate skin. I love that it has a sleeveless design and prefer the style without shoulder snaps. It’s easier to put on and harder for your toddler to take it off. The Mori Sleep Sack features a two-way zipper for easy diaper changes and a sleeveless design that allows for maximum breathability. Its lightweight material makes it perfect for year-round use, and the TOG rating of 0.5 ensures that your baby stays comfortable during warmer months. The Mori Sleep Sack is also available in a range of designs and colors, and makes a great gift. The overall quality and thoughtful design make the Mori Sleep Sack the best option for parents seeking a safe, comfortable, and stylish sleep solution for their baby.



Kyte Baby Sleep Sack

Another great option is the Kyte Baby Sleep Sack. It’s incredibly soft and breathable, and the sleeveless design is easy to put on baby. Made from bamboo rayon, this sleep sack is gentle on sensitive skin and provides excellent temperature regulation. The Kyte Baby Sleep Sack comes in various TOG ratings, so it’s great for different seasons and room temperatures. The Kyte Baby Sleep Sack also features a double zipper for easy diaper changes. With its soft, breathable fabric and thoughtful design, the Kyte Baby Sleep Sack is a fantastic choice for parents seeking a comfortable and safe sleep solution for their baby.



Woolino Sleep Bag

For parents looking for a year-round solution, the Woolino Sleep Bag is an excellent option. Made from 100% natural merino wool, this sleep sack offers excellent temperature regulation. I find it a little more annoying to put on since you have to snap the shoulders, but it’s great for keeping your baby warm in the winter and cool in the summer. Merino wool is known for its moisture-wicking properties, so your baby will stay dry and comfortable all night. The Woolino Sleep Bag comes in a universal 4-season weight (TOG 1.0), making it suitable for room temperatures ranging from 64°F to 75°F.
