Constructed with an Australian merino wool lining, the Woolino sleep sack is naturally temperature regulating.

In summer, the breathable material allows air to circulate, keeping your little one cool.

An extra roomy sack, the Halo offers space for movement and promotes healthy hip development.

Built in the classic style, there’s space for your little one to kick and wiggle as they make themselves comfy for sleep.

Constructed with a roomy design, your toddler can move their hips and legs freely in the night.

This helps with healthy hip development, and gives your child freedom to wiggle around safely.

4. Gunamuna 2.6 TOG Wearable Sleeping Bag

Best Toddler Sleep Sack For Winter

Worried your little one is getting chilly overnight?

The Gunamuna wearable sleeping bag has an incredible 2.6 TOG rating, making it extra cozy for colder months. 

The Gunamuna uses bamboo rayon to create the warmth you’d expect from a down comforter, in a safer design for toddlers and children.

The bamboo rayon is evenly weighted and incredibly fluffy, providing warmth without the bulk.

You and your toddler can breathe easy, knowing the Gunamuna isn’t constricting.

The gentle cocoon shape of the Gunamuna sleeping bag mimics the feeling of a cozy cuddle, while the roomy bag offers space to move.

With extra width and length, your toddler can kick and fold their legs comfortably and safely.

For easy use, the Gunamuna features a WONDERZIP.

Rounded and protected by a zip garage, it’s soft and safe against delicate skin.

It also goes all the way around the sleep sack, and unzips at the bottom.

Late night changes become quicker and easier, especially with the convenient shoulder snaps. 

If cold winters can leave your home chilly, consider the Gunamuna as an easy solution for a comfortable toddler.

Pros

  • 2.6 TOG – Super warm even on cold nights.
  • Bamboo rayon filling – Feels warm without the weight. 
  • WONDERZIP – A safe rounded zip that runs all around the sack, for quicker changes. 

Cons

  • Frequent washing can cause the stitches to come loose. 

5. Tealbee Dreamsuit Wearable Blanket

Best With Arms And Legs

Active toddlers can find the standard sleep sack to be constricting, but it can feel like your only choice when they aren’t ready for blankets.

The Tealbee Dreamsuit offers a simple solution — a wearable blanket with feet that allows for maximum movement.

The Tealbee Dreamsuit is constructed from a premium bamboo rayon and cotton blend, providing a cozy and warming blanket feel.

Lightly padded and quilted, your toddler will love the feeling of being wrapped up in the Dreamsuit. 

And unlike other sleep sacks, with the Dreamsuit, they can move about freely!

The Dreamsuit is built with legs and feet, similar to the onesie.

But because it’s constructed with the quilted rayon blend, it provides the warmth of the blanket.

It’s an excellent blend of safety, convenience, and comfort.

The spacious design allows for optimum movement, although be aware that the suit will shrink slightly with the first wash.

If you’re struggling to keep your little one warm with a blanket, and find they no longer sleep happily in a sack, the Tealbee Dreamsuit is the perfect middle ground.

Pros

  • Bamboo rayon and cotton blend – Warm and breathable, and very soft to the touch.
  • Built-in legs – A little more freedom of movement for growing children.
  • Front zip – Easy on and off.

Cons

  • Small zip covering – Although the zip is protected, some parents have found the covering doesn’t get the job done.

Buyer’s Guide On the best sleep sack for toddler

When your child turns one, they’re finally able to sleep with a blanket! It’s an exciting time of transitions, but that doesn’t mean you need to automatically add bedding to the crib.

If you have a particularly active sleeper, you might find they spend most of the night kicking their blankets away, and wake up cold.

Or, they might stay tucked in all night, and wake up sweaty and grumpy!

If you decide to continue with the sleep sack, you’re likely to find the design that was perfect for your young baby isn’t quite right for your toddler.

Take a look at this buyer’s guide, and learn the features to look for when choosing a sleep sack for a toddler.

Size

Always check the dimensions before buying a toddler sleep sack, as sizes can range significantly between brands.

The sack must be long enough for your toddler to safely stretch their legs, and should have space for movement. 

Toddler sleep sacks typically have room for your little one to grow, and they can seem a little large at first. 

Related to size, a toddler sleep sack also needs to have plenty of room for the hips and legs.

This will allow them to move without feeling constricted. It’s also necessary to ensure hip health!

Material

The best material for a toddler sleep sack is typically dependent on the climate.

If you live somewhere warm, a breathable cotton sack might be best.

For cooler climates, consider a bamboo rayon. 

Avoid synthetic materials, as these can trap hot air and lead to overheating.

Natural materials, such as cotton and wool, are breathable, so air can circulate.

Wool and bamboo are particularly good at regulating temperatures.

Whatever material you choose, make sure it is soft and gentle against your toddlers delicate skin!

A sleep sack is essentially a wearable blanket, so the material should make them feel cozy.

TOG Rating

The TOG rating explains how warm the sleep sack will be.

The higher the TOG rating, the warmer the duvet.

For toddler sleep sacks, the TOG rating is typically around 0.5 to 3.0.

A TOG rating of around 1 tends to be suitable for most sleep sacks.

This is breathable enough for summer, and tends to be warm enough over winter.

If you need a little extra warmth, you can always add a long sleeved onesie underneath! 

If you do live somewhere particularly cold, then you may prefer a higher TOG rating.

However, higher TOG ratings typically offer less versatility.

A high TOG sleep sack is difficult to make cooler in the summer, while a low TOG sack can be made warmer.

Zip/Fastenings

Nearly all sleep sacks come with a zip fastening, and poppers at the shoulders.

These should make the sack easier to get on and off. 

Two-way zippers and wrap around zippers are particularly useful, as these allow you to open the sleep sack without removing it entirely.

You can make a quick diaper change while your toddler stays warm. 

If your little one is particularly adept at zippers, then you might consider an inverted zipper.

These are harder for sneaky hands to get hold of!

Zippers should be covered at the ends. This can prevent the zip from scratching, and prevent chewing and pulling.

Legs

Your toddler is probably starting to become quite active, which means they might feel confined by a sleep sack!

Some toddler sleep sacks come with built-in legs, to accommodate this extra movement.

Consider this if your little one gets frustrated by the standard sleep sack confinement.

However, a sleep sack with legs might not be the right choice if you have a climber.

If your toddler tries to break free from the crib, a standard sleep sack can keep them safer at night.

Consider how much movement your toddler needs when choosing a design.

Care Instructions

Your toddler sleep sack is likely to stay cleaner than your newborn sleep sack, but it will still need a wash from time to time.

Many sleep sacks are machine washable, making them incredibly easy to care for. 

However, some premium designs, such as those made with merino wool, might need a little more care.

If you struggle to find time to hand wash, you might want to stay away from materials that are tricky to clean.

Most toddler sleep sacks will only need the occasional wash, and perhaps a spot clean from time to time.

Design

A sleep sack with a cute design is never going to make a toddler bed time easy, but you might still want to consider print and pattern when making your choice. 

Toddler sleep sacks are available in a range of fun designs.

You can even ask your little one which print they like best!
