The Best Toddler Sleep Sacks for Comfy, Cozy Snoozes
Getting your toddler to go to sleep can be a challenge, to say the least. But, when bedtime rolls around, one thing’s for sure: You’ll want your little one to be comfy, cozy and sleep-safe (whether they’re in your bed or their own). Enter: Toddler sleep sacks. These wearable blankets are just as cozy as their infant counterparts but have been specifically designed with tots in mind. Here, browse top-rated toddler sleep sacks for an array of categories, from quilted and winter styles to lightweight and transitional designs. Plus, read expert-backed advice to ensure your little one is safe as they snooze.
On the hunt for a snuggly toddler sleep sack? As you browse, keep the following tips in mind:
-
Size. Of course, you’ll want to make sure you choose a toddler sleep sack that’s the correct size for your kiddo. To do so, Jillian Thistel—a certified pediatric sleep consultant and founder of Twinkling Stars Pediatric Sleep Consulting in Ontario, Canada—advises parents to check the style’s age, weight and height details before purchasing. It shouldn’t “be too tight and restrictive (which could be uncomfortable and limiting to toddlers), and we also don’t want it to be too loose,” explains Thistel.
-
TOG rating. Unique to sleep-related products, a TOG rating indicates what temperatures the sleep sack is best suited for. As per Thistel, “in the summer months, or in warmer climates, it typically makes sense to use a lighter sleep sack with a lower TOG.” She continues, “in colder climates, or winter months, parents may want to use a warmer sleep sack with a higher TOG.” All in all, you’ll want to ensure that your child is at just the right temperature as they snooze—not too hot or too cold.
-
Material. Thistel recommends choosing toddler sleep sacks that are made from lightweight, comfortable and breathable materials. This is especially important “if a toddler has any type of irritation when it comes to certain fabrics,” she notes.
Many of the safety tips associated with baby sleep sacks, are the same for toddler wearable blankets. According to the American Academy of Pediatrics (AAP), “weighted swaddles, weighted clothing or weighted objects on or near the baby are not safe and not recommended.” This includes weighted sleep sacks, which can potentially be harmful to little ones. Moreover, the AAP advises parents not to use loose blankets or bedding in baby’s sleep environment until they’re at least 12 months old. Thistel also reminds caregivers that “just because toddlers are technically able to sleep with a blanket at 12 months old, it doesn’t mean that they’re ready to do so.” As always, take your child’s unique developmental level into account before introducing a new element into their sleep space. “Toddlers typically do better with understanding the concept of keeping a blanket on when they are around the age of 3 years old (sometimes a bit earlier or even a bit later),” Thistel adds.
With all of that advice in mind, you’re more than ready to start your search. Below, check out the best toddler sleep sacks on the market, from adorable, footed designs to super-soft, lightweight styles.

There isn’t a specific age at which toddlers should stop using sleep sacks. That being said, “it typically makes sense to transition them away from the sleep sack around the time that they transition to a bed (which is usually around the age of 3 years old),” explains Thistel. For some little ones, this transition may take place earlier if the sleep sack is no longer working for them—while others may take longer to part ways with their wearable blankets. Thistel reassures parents that this process will be unique for each kiddo. “We have 3 children (including twin toddlers), our oldest son slept with his sleep sack until the age of 2, one of our twins was ready to transition out of her sleep sack when she was 2.5 years old, and our other twin preferred to stay in her sleep sack until she was 3 years old,” she shares.
Is your tot ready to graduate from a toddler sleep sack and into “big-kid” bedding? “Thankfully the transition out of the sleep sack isn’t usually a challenging transition (especially when compared to the transition out of the swaddle!),” says Thistel. If your child is showing signs of readiness, Thistel suggests letting them know ahead of time that this transition will be taking place. “Having open dialogue can help them prepare, especially if they are very attached to their sleep sack,” she explains. Instead of removing the sleep sack from their bedtime routine all at once, do so gradually. “One strategy that I really love is having the toddler choose a new, small, light blanket that you can introduce, to start getting them used to sleeping with a blanket before you take the sleep sack away completely,” recommends Thistel. When doing this, Thistel advises parents to dress their little ones in a lightweight sleep sack, placing their blanket of choice over them as they rest. This way, they can get used to the idea of sleeping with a blanket. Then, once they’re comfortable with it, you can remove the sleep sack entirely. Lastly, Thistel reminds parents that “it may take some time for your toddler to keep a blanket on all night, and that’s okay! Give them some time and practice to get used to the new change.”
