How Should a Kyte BABY Sleep Bag Fit?

The AAP, or American Academy of Pediatrics recommends that babies sleeping in a crib, sleep in their space alone with no loose blankets. However, they do recommend using a wearable blanket as a safe alternative to loose bedding. See the article here, and excerpt below. Ensuring your wearable blanket is safe and the proper size for your little one is imperative for safety!  There will be a variation among babies because babies come in all shapes and sizes, so everything in this article is just a suggestion or guideline to use.

We never want to size up in sleep bags or buy something they will “grow into” as you risk buying something that is too large to be safe for your little one. Even buying their current size, you’ll get plenty of wear out of it!

If your child is on the high end of the size for the smaller sleep bag, you may be able to size up into the next size.

*Please note that the 0.5 TOG sleep bags are longer than the 1.0 TOG and 2.5 TOG because of the thin fabric without anything between the layers to draw it up and make it shorter in length. The 1.0 TOG will also be slightly longer than a 2.5 TOG for the same reason.

To ensure a proper fit for your Kyte BABY sleep bag, you’ll want to make sure:

  • It isn’t too loose at the neck to pull it over baby’s mouth/nose (and it stay there-- we want to see it falling back down into the correct placement on their chest)
  • It isn’t too loose around the arms/neck that baby can slip into the bag
  • There’s enough space for their legs and hips for proper hip development

A sleep bag can fit well around the chest and still have a lot of length left for them to grow into!

We recommend keeping a minimum 3 sleep bags on hand to rotate through! One to wear, one to wash, and one for extra in case you need to wash both/wait for them to dry!
