How To Choose The Right Baby Sleeping Bag: Everything You Need To Know About Sleeping Bags

The moment your baby is handed to you, sleep becomes essential for you and your little one. Babies need sleep and it is critical for their growth and development. Choosing the right sleeping bag can be an overwhelming task especially with a wide variety available in the market today, but considering key factors such as size, quality, safety, temperature and functionality can make this task a lot easier.

A sleeping bag is a soft, wearable blanket that provides babies of all ages the warmth and comfort of a blanket without the risk of suffocation. As your baby grows out of swaddling and begins to roll, sleep bags fill the gap until they’re ready to switch to a regular blanket throughout their toddler era.   

Home appliances such as night lights, rhythmic sounds like a baby shusher and soothing motion bassinets can be used to create a relaxing environment for the baby. But as great as these appliances can be, a baby needs the comfort of physical contact to ensure a pleasant night’s sleep. This is exactly where the sleep bag comes in handy.

What to consider when choosing a right baby sleeping bag?

Selecting the right size sleeping bag for your little one matters. A well-fitting bag ensures comfort, allows natural leg movement, ensures the baby remains on their back and is designed to reduce the risk of turning over in their sleep thereby reducing suffocation risks. Too big could cover their face; too small might be uncomfortable.

It is important that sleeping bags fit well especially around the shoulders and the neck opening  which should not be too wide so that your baby does not slip into the bag causing a suffocation hazard. It is also best to avoid excess material such as sleeping bags with hoods. 

You may have to fit regularly and consider your baby’s age as the little one is growing so fast amidst all the love and care.

When considering the material, it is best for your baby to sleep in breathable, organic fabrics such as 100% Cotton or bamboo and types of wool. These natural fibers which could prevent overheating compared to synthetic fabrics. 

You could also look out for certain safety standards and certification such as Oeko-Tex certification or comply to safety standard markings such as BS 8510:2009, BS EN 16781:2018.

• TOG and Temperature

Along with choosing the right material, it is important that you first identify the current temperature of your baby’s nursery or room in which they sleep in. By considering the temperature and the different seasons your little one will encounter, you could choose the right TOG rating often found on the labels of your baby sleep bag or clothing that provides the right thermal insulation to keep your baby warm, comfortable and sound asleep.

Also considering the rate at which babies grow, you may want to consider the longevity of the sleep bag. Some sleep bags have additional adjustable features such as zippers or poppers under the arm, that can be used for longer periods of time and adjusted for different stages of your baby’s growth.

Types of baby sleeping bags

When to start using a sleeping bag

Your newborn will most likely be handed to your arms in the hospital all swaddled up and most parents like to continue swaddling as it helps mimic the womb, soothes them and helps them sleep longer. But like any type of baby clothing, your baby will have to transition out of a swaddle. 

This transition often takes place the moment you notice your baby showing signs of rolling which could often happen at around 8 weeks. Rolling in a swaddle is not an option because the moment your baby starts rolling, they need to be able to have their arms free to roll back over. This reduces the risk of suffocation as mobility is no longer restricted.

Transitioning out of a swaddle to a safer option such as a sleep bag can be different for all babies but this could usually be as early as 2 months to 3-6 months old.

Why should you use the best kind of sleeping bag?

There are lots of reasons that you should use a sleepsack for your baby. The most important of which is to create a safe and comfortable sleeping environment. They also assist in regulating your child’s body temperature, helping them stay warm without overheating during the night. Sleep sacks provide comfort like that of being swaddled which enables better sleep by reducing scare awakenings. 

Another reason for dressing your toddler in a sleepsack is that it could prevent your little climber from attempting to escape the crib. When your toddler wears a sleep sack, it becomes especially challenging for them to hoist a leg over the crib’s side, stopping their climbing efforts. The sleep sack’s design restricts their unnecessary movement but instead stays comfortable to sleep through the night.

Are sleeping bags for toddlers safe or not?

When it comes to sleep sack safety. The American Academy of Pediatrics (AAP) suggests using cozy pajamas or a sleep sack for newborns in a safe sleep environment without loose bedding or soft items. Blankets can cause blockage and increase the risk of SIDS. While most sleep sacks are considered safe, it is important to highlight that weighted alternatives should never be used. Weighted sleep sacks are not considered safe for newborns. 

Parents must ensure that the wearable blanket fits their baby snugly when selecting a sleep sack for their baby. It’s critical to avoid fittings that are “excessively large or loose,” as these can threaten small children by increasing the risk of suffocation.
