Overview

Did you know that as many as 3,500 infants die annually in the US because of sleep-related reasons? (1)

Many of these infant deaths are attributed to SIDS (sudden infant death syndrome) and accidental suffocation in bed. (1)

While it might be tempting to put lots of pillows, soft toys, and blankets around your baby to make them more comfortable, doing this could actually be dangerous to your child.

Newborn babies are particularly prone to involuntary movements due to the Moro or startle reflex

In response to a sudden movement or noise, your baby might suddenly extend his arm or arch his back before curling back to the original position.

You shouldn’t worry because this reflex action is natural. But the sudden, jerking movement could move a blanket or pillow over your child’s face and lead to suffocation.

The AAP (American Academy of Pediatrics) recommends that your baby should sleep on a bed with a firm, safe, and sturdy surface. Car seats and strollers shouldn’t be used as your baby’s primary bed. (2)

Also, your baby’s bed should be free from loose blankets, soft toys, crib bumpers, or anything that could cause entrapment, suffocation, or strangulation. (2)

To keep your baby warm and comfortable, you may opt for a sleep sack instead of using regular blankets. 

A wearable baby sleeping bag has a special design. The armholes let your baby wear the upper part like regular clothes, but the lower portion is a snug blanket that’s secured by a zipper.

These 2-in-1 sleepwear-and-blankets aren’t just for babies but for toddlers and older kids, too.

You can find our top choices for wearable blankets and toddler sleep sacks below.

 

The Top 15 Toddler Sleep Sacks & Wearable Blankets

In choosing sleep sacks, sleepwear, and other garments for your baby, it’s a good idea to check the TOG (Thermal Overall Grade) rating. 

This unit of measurement is used to show the level of warmth and insulation that a garment can give your baby:

  • A lower TOG rating can keep your child cooler; best for warm or hot summer months
  • A higher TOG rating can keep your child warm; best for colder winter months

 

Note that wearing clothes with higher TOG can lead to overheating, especially during hot or humid days. So, it’s still best to check the body temperature of your little one.

Here’s a handy guide to the ideal room temperature based on the sleepwear’s TOG ratings:

  • 0.2 TOG: between 75°F and 81°F
  • 1.0 TOG: between 68°F to 75°F
  • 2.5 TOG: between 61°F to 68°F
  • 3.5 TOG: below 61°F

I liked the idea of this product for my 6-month-old, but, man, it is hard work getting my wriggly one into (one during) nighttime, and tantrums are assured. I would recommend a full-length zipper for easy access as the current half-length is a struggle.” – Reviewer on the ErgoPouch website.

Toddler Sleep Sack FAQs

Are Sleep Sacks Safe?

Wearable blankets may be safer than loose blankets because your baby wears the upper part, ensuring that the blanket won’t cover their face.

Are Sleep Sacks Alright for Babies Who Can Rollover?

These baby sleeping bags typically move along with your baby’s movement but also provide better legroom.

Why Are Sleep Sacks Sleeveless?

The armholes of the sleeveless sleep sacks can help provide better airflow and circulation, preventing overheating.

When Should Your Kids Stop Using Sleep Sacks?

There’s no specific deadline over when kids should stop using sleep sacks. Often, the decision may lie on an older child’s preference to wear one or picking a loose blanket.

 

Summary & Recommendation 

In choosing sleepwear, blankets, sleeping bags, and other items your baby needs for sleeping, you should always consider comfort and safety.

Many parents also consider the price tag and whether the clothing item can adjust with the child’s growth.

Organic, chemical-free sleeping bags may be safer options for your little one, but they’re usually more expensive. 

But different parents might prefer different kinds of toddler sleep sacks, depending on their babies’ needs.
