When should I stop swaddling my baby?

As your baby grows, they will outgrow their need for swaddling. It's time to stop swaddling your baby as they start to show signs of "breaking out" of the swaddle, when they begin to move about the cot and roll over, or when they to prefer to have their arms free. To ease the transition for the baby, you can start introducing the HALO® SleepSack® Sleeping Bag.

How do I transition my baby from swaddling to a SleepSack® Sleeping Bag?

When your baby shows signs of breaking free from the SleepSack® Swaddle or rolling over, it’s time to discontinue swaddling. To make the transition easier, we recommend gradually transitioning your little one to the SleepSack® Sleeping Bag. You can do this by swaddling your baby for a few nights with one arm out, then two arms out of the swaddle. Your baby will still have the secure feeling of the swaddle while gradually adjusting to having his arms free.

Can I start using a larger-sized SleepSack® Swaddle on my newborn and then he/she can just grow into it?

We do not recommend using a SleepSack® Swaddle that does not correspond to your baby’s current size. The purpose of the swaddle is to keep your baby from having any excess material that may bundle up around baby’s nose or mouth. If the baby is wearing a swaddle that is too large, there is a potential for the baby's head to slip through the neck hole or for excess material to bundle up around his or her face.

How does the SleepSack® Swaddle help babies sleep safely?

The SleepSack® Swaddle replaces loose blankets in the cot that can cover a baby’s face and interfere with breathing. It also helps reduce the risk of baby overheating.

Why is the SleepSack® Swaddle sleeveless?

It is sleeveless to reduce the chance of baby overheating and is easier to be worn with regular sleepwear underneath.

How do I use the SleepSack® Sleeping Bag?
Slip the SleepSack® Swaddle Sleeping Bag over your baby's regular sleepwear as a replacement to loose blankets in the cot.
