Sleep sacks are the perfect way to ensure your baby or toddler stays cozy and warm without overheating. Even the hospital where I delivered my babies understands the value of sleep sacks —every newborn goes home with one! They truly are the best alternative to loose blankets, which aren't safe for babies and can be tricky for toddlers who move around like crazy in their sleep.

If your little one is growing out of their sleep sacks and entering toddlerhood , but you're not ready for blankets just yet, there are a variety of sleep sacks that come in extended sizes.

Wearable blankets aren't just a must-have for infants, they're a great option for toddlers, too.

Plus, a toddler that wears a sleep sack can't really climb out of the crib the way a toddler without the sleep sack barrier might be able to...just saying! Warmth isn't the only reason we love toddler sleep sacks.

Without further ado, here is a roundup of the best toddler sleep sacks so you and your kiddo can sleep safely and soundly all night long.

MiliMili $48

Kona Banana Wearable Blanket

MiliMili knocks it out of the park with all their colorful sleep sacks, but the Kona Banana print is our ultimate favorite. The adorable wearable blanket is soft, comfy, and made from high-quality bamboo jersey fabric, which is great for toddlers’ sensitive skin. There’s a dual zipper, which means it opens at the top and the bottom so zipping up at bedtime or after a diaper change is a cinch! There’s a tab that covers the zipper so it protects your toddler’s chin and keeps them from unzipping themselves through the night. As one of the longest on the market, it will fit kids up to 42″tall.

Seatbelt slots that make the transition from car ride naps to bedtime bliss easy-peasy. (Well, as easy as it ever is, right?)
