The toddler years are an age when a baby can no longer be swaddled, but also cannot have a blanket in the crib. You need something to keep your toddler warm and cozy, while also not overheating.

That is where toddler sleep sacks come in! A normal blanket can be a hazard if your toddler still sleeps in a crib. His or her face could get covered causing suffocation.

As a mom of 3, I absolutely loved using sleep sacks for my toddlers. That is why I decided to assemble this list of the best toddler sleep sacks and extra large sleep sacks. I want to help other toddler parents determine which sleep sacks work the best, which ones have the best quality, and actually work.

What Are Toddler Sleep Sacks?

A sleep sack is a kind of wearable blanket that replaces swaddles and normal blankets. It can be made of pure cotton, wool, fleece, or a blend of these fabrics. The real purpose of a sleep sack is to keep your toddler warm under covers, while still allowing him to move his arms and legs freely.

Other Names For Toddler Sleep Sacks

Toddler sleep sacks are also called:

  • Wearable blankets – in other words your toddler wears it, but it still acts as a blanket
  • Sleeping bags – bag-like structures in which your toddler sleeps

Are Sleep Sacks Safe for Toddlers?

Sleep sacks for kids are actually made to ensure safety. Your toddler will wear it almost like a dress. He will be able to move, but he won’t get out of it or cover his face with it.

These qualities mean it actually reduces the risk of SIDS, when compared to a traditional blanket for a bed. Be sure to choose the right size and material so that your baby’s body temperature is regulated properly and it is indeed safe.

Why Should I Use a Toddler Wearable Blanket?

I found toddler sleep sacks give you peace of mind, but I also found them to have a lot of benefits even besides safety. Here we review both the safety benefits and other advantages.

  • Being covered helps your toddler’s body temperature regulate. Your toddler can stay warm while sleeping without the risk of overheating.
  • No need to get up several times at night to adjust a blanket.
  • Your toddler will be able to move around freely without the risk of suffocation.
  • It gives a secure feeling to toddlers.
  • Your toddler is less likely to try to climb out of the crib because his feet are not accessible.
  • Using a toddler sleep sack is a great inclusion for your bedtime routine.
  • Helps your toddler sleep better on vacation or when you are away from home.

What Does TOG For Toddler Sleep Sacks Mean?

We have been talking about a sleep sack’s TOG but what is that? TOG stands for “thermal overall grade”. This term is a standard used in the textile industry to indicate the warmth of a garment. In other words it measures how warm a garment can keep a person wearing it.

TOG is rated anywhere from 0.25 to 13.5, with 0.25 being the coldest and 13.5 the warmest. For baby garments, the TOG rating will be a maximum of 3.5. To give you an idea of how the scale works, a 13.5 TOG is the equivalent of a winter weight duvet.

It’s very important to consider the TOG rating when you are buying sleeping bags for your baby. To go along with that you should consider the weather and room temperature as well.

When Can I Start Using a Sleeping Sack?

When your baby starts to roll over or is able to open his swaddle with kicking or hand movements, is a common time when parents switch from swaddles to sleep sacks. This typically happens around 3-4 months of age. However, you can choose to use sleep sacks with swaddles attached from the time your baby is a newborn.

So, really you can start using a sleep sack with your baby from day 1. But, that is not necessarily what you need to do.

Personally in my house, we started with swaddling blankets, switched to a baby Merlin sleep suit, then around 7 months old moved our kids into sleep sacks. They stayed in their sleep sacks until we moved them from a crib to a bed around age 3.

When Should I Take My Toddler Out Of a Sleep Sack?

Sleep sacks are designed to keep your baby or toddler safe, comfortable, and covered while sleeping. When you see that your child doesn’t need these features anymore you can take him out of the sleep sack.

There is no rule of thumb, but typically when your toddler is no longer in a crib and sleeps in a regular-sized bed, you can switch from a sleep sack to a blanket.

If your toddler is not comfortable in a sleep sack, maybe he feels confined and restless, you can stop using them earlier or change the style of the sack. For example, from bag-shaped to the sack with foot openings.
