Best Wearable Blanket – Keeping Baby Safe at Night

Best wearable blankets

Finding the best wearable blanket does not have to be a tedious task of trial and error. Use this guide to help you find the perfect sleep sack for your child.

Why should you use a wearable blanket?

Babies often cry through the night because they're used to the warmth of the womb. Such is the reason why many moms engage in the practice of swaddling, which can be time consuming.

Wearable blankets eliminate the need to battle with traditional swaddle cloths all while providing the comfort that newborns need to get a restful night’s sleep.

Sleeping sacks also combat what is known as “startle reflex,” which occurs when the little one’s head drops backward.

Such sporadic movement causes the neck to extend, which convinces the body that the baby is falling. The little one's arms, in response to such perceived danger, involuntarily flail outwards in desperation, which can upset, and wake, the child.

What are advantages and disadvantages of sleep sacks?

One significant advantage of sleeping sacks is their ability to eliminate the need for loose blankets in the crib. Your baby can comfortably rest without you worrying about them smothering under the weight of other cloths.

Another advantage of wearable blankets is their breathability. Sudden infant death syndrome (SIDS) is sometimes brought about by rising temperatures caused by blankets. Many manufacturers of wearable sleeping sacks are aware of such findings and strive to make products that maintain a balance of body temperatures through the night.

One disadvantage of wearable blankets is their ability to cause hip dysplasia: an acute orthopedic issue in which the hip’s socket is too shallow.

Avoiding this problem is a matter of parents finding the right wearable blanket size for their newborns and trading up to the next size when the little one outgrows the first sleeping sack.​

What should you look for when buying a wearable blanket?

You should pay attention to the following when searching for the ideal wearable blanket:​

  • Size - Make sure that the sleeping sack fits your baby perfectly. Do not try to save money by purchasing an oversized blanket, as such a budgeting tactic undermines the purpose of the wearable blanket.
  • Temperature Range - Most blankets have a thermal score known as TOG listed. Sacks with high TOG scores should be avoided, while those with low score should be embraced. Generally speaking, a TOG score between 0.5 and 2.5 is ideal.
  • Safety - Zippers that zip from top to bottom provide versatility and ensure that baby cannot get to them when he becomes curious. Also on the security list are materials that are organic. You do not want to dress your child in fabric that is flammable or prone to cause a rash.
  • Comfort - Do not exchange warmth for manageability. Your baby’s wearable blanket should be both thick and soft.
